Abstract PDF: Background
This study aimed to reclassify a subset of poorly differentiated salivary gland carcinoma that do not conform to any entities of the current World Health Organization (WHO) classification into the category of undifferentiated carcinoma (UDC) because they lack specific histologic differentiation or immunophenotype. Methods: Cases of salivary gland carcinomas from Asan Medical Center (2002–2020) that did not fit any existing WHO classification criteria and were diagnosed as poorly differentiated carcinoma, high-grade carcinoma, or UDC, were retrospectively reviewed. Immunohistochemical (IHC) staining for p40, neuroendocrine markers, androgen receptor (AR), and gross cystic disease fluid protein 15 (GCDFP-15) and Epstein-Barr virus (EBV) in situ hybridization (ISH) were performed. Clinical data were collected from the electronic medical records. Results: Six salivary gland carcinomas did not align with any specific entities and lacked distinct differentiation. Two of six cases displayed lymphoepithelial carcinoma (LEC)-like morphology but were negative or showed negligible immunoreactivity for p40 and EBV ISH, distinguishing them from LEC of the salivary gland. Two cases showed strong AR positivity, suggesting a potential overlap with salivary duct carcinoma (SDC) but lacked classic SDC morphologies and GCDFP-15 expression. No cases expressed neuroendocrine markers. Conclusions: This study proposes reclassifying these poorly differentiated or high-grade salivary gland carcinomas as UDC based on their indeterminate differentiation and IHC profiles. This may lead to a clearer diagnostic category and enhance our understanding of these high-grade tumors.

Cervical cancer screening during pregnancy presents unique challenges for cytologic interpretation. This review focuses on pregnancy-associated cytomorphological changes and their impact on diagnosis of cervical intraepithelial neoplasia (CIN) and cervical cancer. Pregnancy-induced alterations include navicular cells, hyperplastic endocervical cells, immature metaplastic cells, and occasional decidual cells or trophoblasts. These changes can mimic abnormalities such as koilocytosis, adenocarcinoma in situ, and high-grade squamous intraepithelial lesions, potentially leading to misdiagnosis. Careful attention to nuclear features and awareness of pregnancy-related changes are crucial for correct interpretation. The natural history of CIN during pregnancy shows higher regression rates, particularly for CIN 2, with minimal risk of progression. Management of abnormal cytology follows modified risk-based guidelines to avoid invasive procedures, with treatment typically deferred until postpartum. The findings reported in this review emphasize the importance of considering pregnancy status in cytological interpretation, highlight potential problems, and provide guidance on differentiating benign pregnancy-related changes from true abnormalities. Understanding these nuances is essential for accurate diagnosis and proper management of cervical abnormalities in pregnant women.

Abstract PDF

Primary renal myoepithelial carcinoma is an exceedingly rare neoplasm with an aggressive phenotype and Ewing sarcoma breakpoint region 1 (EWSR1) rearrangement in a small fraction of cases. In addition to its rarity, the diagnosis can be challenging for the pathologist due to morphologic heterogeneity, particularly on the biopsy specimen. At times, immunohistochemistry may be indecisive; therefore, molecular studies should be undertaken for clinching the diagnosis. We aim to illustrate a case of primary myoepithelial carcinoma of the kidney with EWSR1-rearrangement in a 67-year-old male patient who presented with right supraclavicular mass, which was clinically diagnosed as carcinoma of an unknown primary. An elaborate immunohistochemical work-up aided by fluorescent in-situ hybridization allowed us to reach a conclusive diagnosis. This unusual case report advocates that one should be aware of the histological mimickers and begin with broad differential diagnoses alongside sporadic ones and then narrow them down with appropriate ancillary studies.

Abstract PDF

The development and standardization of cytologic screening of the uterine cervix has dramatically decreased the prevalence of squamous cell carcinoma of the uterine cervix. Advances in the understanding of biology of human papillomavirus have contributed to upgrading the histologic diagnosis of the uterine cervix; however, cytologic screening that should triage those that need further management still poses several difficulties in interpretation. Cytologic features of high grade intraepithelial squamous lesion (HSIL) mimics including atrophy, immature metaplasia, and transitional metaplasia, and glandular lesion masquerades including tubal metaplasia and HSIL with glandular involvement are described with accentuation mainly on the differential points. When the cytologic features lie in a gray zone between the differentials, the most important key to the more accurate interpretation is sticking to the very basics of cytology; screening the background and cellular architecture, and then scrutinizing the nuclear and cytoplasmic details.

Abstract PDF

Background
Detection of glandular abnormalities in Papanicolaou (Pap) tests is challenging. This study aimed to review our institute’s experience interpreting such abnormalities, assess cytohistologic concordance, and identify cytomorphologic features associated with malignancy in follow-up histology.
Methods
Patients with cytologically-detected glandular lesions identified in our pathology records from 1995 to 2020 were included in this study.
Results
Of the 683,197 Pap tests performed, 985 (0.144%) exhibited glandular abnormalities, 657 of which had tissue follow-up available. One hundred eighty-eight cases were cytologically interpreted as adenocarcinoma and histologically diagnosed as malignant tumors of various origins. There were 213 cases reported as atypical glandular cells (AGC) and nine cases as adenocarcinoma in cytology, yet they were found to be benign in follow-up histology. In addition, 48 cases diagnosed with AGC and six with adenocarcinoma cytology were found to have cervical squamous lesions in follow-up histology, including four squamous cell carcinomas. Among the cytomorphological features examined, nuclear membrane irregularity, three-dimensional clusters, single-cell pattern, and presence of mitoses were associated with malignant histology in follow-up.
Conclusions
This study showed our institute’s experience detecting glandular abnormalities in cervical cytology over a 25-year period, revealing the difficulty of this task. Nonetheless, the present study indicates that several cytological findings such as membrane irregularity, three-dimensional clusters, single-cell pattern, and evidence of proliferation could help distinguishing malignancy from a benign lesion.

Background
Human papillomavirus (HPV) infection is a major cause of cervical cancer and associated precursor lesions. Multiple HPV genotype infections have been reported. However, their clinicopathological characteristics still remain elusive.
Methods
For this study, 814 consecutive patients who had undergone colposcopy and HPV genotyping test using BD Onclarity HPV assay were retrospectively selected. Clinicopathological parameters of multiple HPV infections were compared with those of single HPV infection.
Results
Multiple HPV infections were found in 110 out of 814 cases (13.5%). Multiple HPV infections were associated with a significantly higher incidence of high-grade intraepithelial lesions (HSILs) compared with single HPV infection. Other high-risk HPV genotypes, in addition to HPV 16, were found more frequently in the multiple HPV infections group; these included HPV 51, 52, 33/58, 56/59/66, and 35/39/68. No specific coinfection pattern was not identified. Additionally, the number of HPV genotypes in multiple HPV infections was not associated with the progression to HSIL or squamous cell carcinoma.
Conclusions
Multiple HPV infections have distinct clinicopathological characteristics (compared with single HPV infection). As their biological behavior is uncertain, close and frequent follow-up is warranted.

Abstract PDF

Background
Ovarian epithelial cancer (OEC) is the second-most common gynecologic malignancy. CD109 expression is elevated in human tumor cell lines and carcinomas. A previous study showed that CD109 expression is elevated in human tumor cell lines and CD109 plays a role in cancer progression. Therefore, this study aimed to determine whether CD109 is expressed in OEC and can be useful in predicting the prognosis.
Methods
Immunohistochemical staining for CD109 and reverse transcription-quantitative polymerase chain reaction was performed. Then we compared CD109 expression and chemoresistance, overall survival, and recurrence-free survival of OEC patients. Chemoresistance was evaluated by dividing into good-response group and poor-response group by the time to recurrence after chemotherapy.
Results
CD109 expression was associated with overall survival (p = .020), but not recurrence-free survival (p = .290). CD109 expression was not an independent risk factor for overall survival due to its reliability (hazard ratio, 1.58; p = .160; 95% confidence interval, 0.82 to 3.05), although we found that CD109 positivity was related to chemoresistance. The poor-response group showed higher rates of CD109 expression than the good-response group (93.8% vs 66.7%, p = .047). Also, the CD109 mRNA expression level was 2.88 times higher in the poor-response group as compared to the good-response group (p = .001).
Conclusions
Examining the CD109 expression in patients with OEC may be helpful in predicting survival and chemotherapeutic effect.

Abstract PDF

Focal segmental glomerulosclerosis (FSGS) is characterized by focal and segmental obliteration of glomerular capillary tufts with increased matrix. FSGS is classified as collapsing, tip, cellular, perihilar and not otherwise specified variants according to the location and character of the sclerotic lesion. Primary or idiopathic FSGS is considered to be related to podocyte injury, and the pathogenesis of podocyte injury has been actively investigated. Several circulating factors affecting podocyte permeability barrier have been proposed, but not proven to cause FSGS. FSGS may also be caused by genetic alterations. These genes are mainly those regulating slit diaphragm structure, actin cytoskeleton of podocytes, and foot process structure. The mode of inheritance and age of onset are different according to the gene involved. Recently, the role of parietal epithelial cells (PECs) has been highlighted. Podocytes and PECs have common mesenchymal progenitors, therefore, PECs could be a source of podocyte repopulation after podocyte injury. Activated PECs migrate along adhesion to the glomerular tuft and may also contribute to the progression of sclerosis. Markers of activated PECs, including CD44, could be used to distinguish FSGS from minimal change disease. The pathogenesis of FSGS is very complex; however, understanding basic mechanisms of podocyte injury is important not only for basic research, but also for daily diagnostic pathology practice.

Abstract PDF

Background
Developing predictive markers for hepatocellular carcinoma (HCC) is important, because many patients experience recurrence and metastasis. Epithelial to mesenchymal transition (EMT) is a developmental process that plays an important role during embryogenesis and also during cancer metastasis. Paired-related homeobox protein 1 (Prrx-1) is an EMT inducer that has recently been introduced, and its prognostic significance in HCC is largely unknown.
Methods
Tissue microarray was constructed using surgically resected primary HCCs from 244 cases. Immunohistochemical staining of E-cadherin and Prrx-1 was performed. The correlation between E-cadherin loss and Prrx-1 expression, as well as other clinicopathologic factors, was evaluated.
Results
E-cadherin expression was decreased in 96 cases (39.4%). Loss of E-cadherin correlated with a higher recurrence rate (p < .001) but was not correlated with patient’s survival. Thirty-two cases (13.3%) showed at least focal nuclear Prrx-1 immunoreactivity while all non-neoplastic livers (n = 22) were negative. Prrx-1 expression was not associated with E-cadherin loss, survival or recurrence rates, pathologic factors, or the Ki-67 labeling index. Twenty tumors that were positive for E-cadherin and Prrx-1 had significantly higher nuclear grades than the rest of the cohort (p = .037). In Cox proportional hazard models, E-cadherin loss and large vessel invasion were independent prognostic factors for shorter disease-free survival. Cirrhosis and high Ki-67 index (> 40%) were independent prognostic factors for shorter overall survival.
Conclusions
Prrx-1 was expressed in small portions of HCCs but not in normal livers. Additional studies with a large number of Prrx-1-positive cases are required to confirm the results of this study.

Abstract PDF

Background
Human papillomavirus (HPV) is a major risk factor for cervical cancer.
Methods
We evaluated the clinical significance of the HPV DNA chip genotyping assay (MyHPV chip, Mygene Co.) compared with the Hybrid Capture 2 (HC2) chemiluminescent nucleic acid hybridization kit (Digene Corp.) in 867 patients.
Results
The concordance rate between the MyHPV chip and HC2 was 79.4% (kappa coefficient, κ = 0.55). The sensitivity and specificity of both HPV tests were very similar (approximately 85% and 50%, respectively). The addition of HPV result (either MyHPV chip or HC2) to cytology improved the sensitivity (95%, each) but reduced the specificity (approximately 30%, each) compared with the HPV test or cytology alone. Based on the MyHPV chip results, the odds ratio (OR) for ≥ high-grade squamous intraepithelial lesions (HSILs) was 9.9 in the HPV-16/18 (+) group and 3.7 in the non-16/18 high-risk (HR)-HPV (+) group. Based on the HC2 results, the OR for ≥ HSILs was 5.9 in the HR-HPV (+) group. When considering only patients with cytological diagnoses of “negative for intraepithelial lesion or malignancy” and “atypical squamous cell or atypical glandular cell,” based on the MyHPV chip results, the ORs for ≥ HSILs were 6.8 and 11.7, respectively, in the HPV-16/18 (+) group.
Conclusions
The sensitivity and specificity of the MyHPV chip test are similar to the HC2. Detecting HPV-16/18 with an HPV DNA chip test, which is commonly used in many Asian countries, is useful in assessing the risk of high-grade cervical lesions.

Abstract PDF

Background
Parafibromin is a product of the tumor suppressor gene that has been studied as a potential indicator of tumor aggressiveness in the parathyroid, breast, colorectum, and stomach. However, the clinical significance and potential function of parafibromin expression in head and neck squamous cell carcinomas remain largely unknown. The aim of this study was to evaluate the expression of parafibromin in laryngeal squamous cell carcinoma (LSCC) and to verify its potential as a biomarker of tumor behavior.
Methods
Parafibromin expression was evaluated in 30 cases of LSCC using immunohistochemistry. The correlations between parafibromin expression and clinicopathologic parameters were investigated.
Results
Parafibromin expression was positive in 15 cases (50%) and negative in 15 cases (50%). Tumor size and T stage showed a statistically significant inverse relationship with parafibromin expression (p=.028 and p<.001, respectively). Parafibromin expression was not associated with age, sex, lymph node metastasis, tumor differentiation, or tumor location. There was no statistically significant relationship between parafibromin expression and progression-free survival in the patients (p>.05).
Conclusions
Our results indicate that the downregulation or loss of parafibromin expression can be employed as a novel marker of tumor progression or aggressiveness in LSCC.

Abstract PDF

Background
Aquaporin 1 (AQP1) overexpression has been shown to be associated with uncontrolled cell replication, invasion, migration, and tumor metastasis. We aimed to evaluate AQP1 expression in lung adenocarcinomas and to examine its association with clinicopathological features and prognostic significance. We also investigated the association between AQP1 overexpression and epithelial-mesenchymal transition (EMT) markers.
Methods
We examined AQP1 expression in 505 cases of surgically resected lung adenocarcinomas acquired at the Seoul National University Bundang Hospital from 2003 to 2012. Expression of AQP1 and EMT-related markers, including Ecadherin and vimentin, were analyzed by immunohistochemistry and tissue microarray.
Results
AQP1 overexpression was associated with several aggressive pathological parameters, including venous invasion, lymphatic invasion, and tumor recurrence. AQP1 overexpression tended to be associated with higher histological grade, advanced pathological stage, and anaplastic lymphoma kinase (ALK) translocation; however, these differences were not statistically significant. In addition, AQP1 overexpression positively correlated with loss of E-cadherin expression and acquired expression of vimentin. Lung adenocarcinoma patients with AQP1 overexpression showed shorter progression- free survival (PFS, 46.1 months vs. 56.2 months) compared to patients without AQP1 overexpression. Multivariate analysis confirmed that AQP1 overexpression was significantly associated with shorter PFS (hazard ratio, 1.429; 95% confidence interval, 1.033 to 1.977; p=.031).
Conclusions
AQP1 overexpression was thereby concluded to be an independent factor of poor prognosis associated with shorter PFS in lung adenocarcinoma. These results suggested that AQP1 overexpression might be considered as a prognostic biomarker of lung adenocarcinoma.

Abstract PDF

Dysembryoplastic neuroepithelial tumor (DNT) is a benign glioneuronal neoplasm that most commonly occurs in children and young adults and may present with medically intractable, chronic seizures. Radiologically, this tumor is characterized by a cortical topography and lack of mass effect or perilesional edema. Partial complex seizures are the most common presentation. Three histologic subtypes of DNTs have been described. Histologically, the recognition of a unique, specific glioneuronal element in brain tumor samples from patients with medically intractable, chronic epilepsy serves as a diagnostic feature for complex or simple DNT types. However, nonspecific DNT has diagnostic difficulty because its histology is indistinguishable from conventional gliomas and because a specific glioneuronal element and/or multinodularity are absent. This review will focus on the clinical, radiographic, histopathological, and immunohistochemical features as well as the molecular genetics of all three variants of DNTs. The histological and cytological differential diagnoses for this lesion, especially the nonspecific variant, will be discussed.

Abstract PDF

Background

Epithelial-mesenchymal transition (EMT) is associated with tumor hypoxia. EMT is regulated, in part, by the action of TWIST, which inhibits of E-cadherin expression and may interfere with the p53 tumor-suppressor pathway.

Methods

We examined the expression of TWIST, E-cadherin, hypoxia-inducible factor 1α (HIF1α), and p53 by immunohistochemistry in 123 cases of ovarian epithelial cancers (OEC) to evaluate the role of TWIST in OEC. We assessed the association between protein expression and clinicopathologic parameters.

Results

The expression of TWIST, E-cadherin, HIF1α, and p53 proteins was found in 28.5%, 51.2%, 35.0%, and 29.3% of cases, respectively. TWIST expression was associated with higher histologic grade and unfavorable survival. TWIST expression was correlated with HIF1α expression and reduced E-cadherin expression. The altered HIF1α/TWIST/E-cadherin pathway was associated with lower overall survival (OS), while the co-expression of TWIST and p53 was correlated with lower progression-free survival. In the multivariate analyses, TWIST expression was an independent prognostic factor for OS.

Conclusions

Our data imply that TWIST expression could be a useful predictor of unfavorable prognosis for OEC. TWIST may affect the p53 tumor-suppressor pathway. Moreover, hypoxia-mediated EMT, which involves the HIF1α/TWIST/E-cadherin pathway may play an important role in the progression of OEC.

Abstract PDF

Background

Epithelial-mesenchymal transition (EMT) is an important step in the invasion and progression of cancer and in the development of chemoresistance by cancer cells.

Methods

To address the clinical significance of the EMT pathway in lung adenocarcinoma and the association of the pathway with histological subtype, we examined 193 surgically resected lung adenocarcinoma samples for the expression of representative EMT-related proteins (E-cadherin, β-catenin, and vimentin) by immunohistochemistry. Histological subtypes were classified according to the 2011 International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society classification. The results for EMT-related protein expression were analyzed for correlation with clinicopathological features and with survival.

Results

The loss of E-cadherin expression and aberrant β-catenin expression were significantly associated with larger tumor size, pleural invasion, lymphatic/vascular invasion, and advanced pathological stage (p<0.05). The alteration of the E-cadherin/β-catenin complex was least frequently observed in the lepidic-predominant group, but these associations were not statistically significant. In the multivariate analysis, altered E-cadherin/β-catenin complex expression was found to be an independent poor prognostic factor (p=0.017; hazard ratio, 1.926; 95% confidence interval, 1.119 to 3.314).

Conclusions

The alteration of the expression of the E-cadherin/β-catenin complex was associated with aggressive tumor behavior in lung adenocarcinoma.

Abstract PDF

Background

Tumor hypoxia is associated with malignant progression and treatment resistance. Hypoxia-related factors, such as carbonic anhydrase IX (CA IX), glucose transporter-1 (GLUT-1), and vascular endothelial growth factor (VEGF) permit tumor cell adaptation to hypoxia. We attempted to elucidate the correlation of these markers with variable clinicopathological factors and overall prognosis.

Methods

Immunohistochemistry for CA IX, GLUT-1, and VEGF was performed on formalin-fixed, paraffin-embedded tissues from 125 cases of ovarian epithelial cancer (OEC).

Results

CA IX expression was significantly associated with an endometrioid and mucinous histology, nuclear grade, tumor necrosis, and mitosis. GLUT-1 expression was associated with tumor necrosis and mitosis. VEGF expression was correlated only with disease recurrence. Expression of each marker was not significant in terms of overall survival in OECs; however, there was a significant correlation between poor overall survival rate and high coexpression of these markers.

Conclusions

The present study suggests that it is questionable whether CA IX, GLUT-1, or VEGF can be used alone as independent prognostic factors in OECs. Using at least two markers helps to predict patient outcomes in total OECs. Moreover, the inhibition of two target gene combinations might prove to be a novel anticancer therapy.

Abstract PDF

Fibroepithelial stromal polyp (FSP) is a benign lesion that can occur at various sites, including the lower female genital tract. In rare cases, however, it may exhibit hypercellularity, bizarre cytomorphological features, and atypical mitoses resulting in an overdiagnosis as a malignant tumor despite its benign clinical course. Recently, we experienced one case of a 30-year-old pregnant woman with cellular pseudosarcomatous FSP that was initially diagnosed as a malignant fibrous histiocytoma at a primary clinic. In addition to describing the rare features of this case, we wish to increase awareness about this benign lesion which will be essential for avoiding unnecessary radical surgery or chemoradiation treatment.

Abstract PDF

Background

Epithelial-mesenchymal transition (EMT) has been known to play a key role in the stromal invasion of carcinoma in situ (CIS) lesion. Loss of E-cadherin and acquisition of vimentin are two critical steps in EMT, that are induced by Snail-1 upregulation associated with overexpression of epidermal growth factor receptor (EGFR). However, roles of EMT-related proteins in human cervical tissues have not been fully elucidated. In this study, we investigated the immunoexpressions of EMT-related proteins in CIS, microinvasive squamous cell carcinoma (SCC), and invasive SCC to demonstrate their key roles in tumor progression.

Methods

Eighty one CIS, 17 microinvasive, and 21 invasive SCC cases were immunostained with primary antibodies for Snail-1, EGFR, E-cadherin, and vimentin on paraffin-embedded tissue microarray blocks.

Results

EGFR and Snail-1 proteins were highly expressed but the levels were not significantly different between the three groups. However, loss of E-cadherin and acquisition of vimentin were proven to occur significantly higher in microinvasive and invasive SCC cases than in CIS.

Conclusions

E-cadherin and vimentin were found to be two useful indicators of EMT in evaluating stromal invasion of CIS. However, it was not demonstrated for Snail-1 and EGFR proteins to play any key role in the progression of cervix cancer.

Abstract PDF

Background

About 10% of high-grade squamous intraepithelial lesions (HSILs) progress to invasive carcinomas within 2-10 years. By delineating the events that occur in the early stage of the invasion, the pathogenesis of cervical cancer could be better understood. This will also propose the possible methods for inhibiting the tumor invasion and improving the survival of patients.

Methods

We compared the genomic profiles between the HSIL and the invasive squamous cell carcinoma (SCC) using an array comparative genomic hybridization. Using recurrently altered genes, we performed a principal component analysis to see variation of samples in both groups. To find possibly affected pathways by altered genes, we analyzed genomic profiles with the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway database and GOEAST software.

Results

We found 11q12.3 and 2p24.1 regions have recurrent copy number gains in both groups. 16p12-13 and 20q11-13 regions showed an increased copy number only in cases of HSIL. 1q25.3 and 3q23-29 regions showed copy number gains only in cases of SCC. Altered genes in the SCC group were related to the mitogen-activated protein kinase signaling pathway and the RNA transport. Altered genes in the HSIL group were related to the ubiquitin mediated proteolysis and cell adhesion molecules.

Conclusions

Our results showed not only that gains in 11q12.3 and 2p24.1 were early events occurring in the premalignant lesions and then maintained in cases of SCC but also that gains in 1q25.3 and 3q23-29 were late events occurring after invasion in those of SCC.

Abstract PDF

Cutaneous myoepithelial neoplasms and papillary eccrine adenomas (PEA) are rare conditions. Malignant tumors within a PEA are even rarer, with only one case reported to date. Herein, we present an extremely rare case of a cutaneous myoepithelial carcinoma arising in a PEA in a 70-year-old man presenting a solid mass in the left buttock. Histopathologically, most of the resected tumor revealed features consistent with the diagnosis of PEA. Some small nests and nodules were intermixed with the PEA and were present adjacent to the PEA. The tumor cells of nests and nodules showed ovoid to spindle shaped nuclei and slightly eosinophilic cytoplasm. Immunohistochemically, they were positive for both epithelial and myogenic markers, consistent with myoepithelioma. An inguinal lymph node with a metastatic lesion showed the same findings of myoepithelioma despite inconspicuous atypia. Our case showed malignant transformation of the myoepithelial cells at the outermost layers of the PEA.

Abstract PDF: BACKGROUND
Idiopathic duct centric pancreatitis (IDCP) is a subtype of autoimmune pancreatitis (AIP) that is histologically characterized by granulocytic epithelial lesion and scarce IgG4-positive cells. This subtype of AIP has not been documented in Asian countries.
METHODS
We reviewed 38 histologically confirmed AIP cases and classified them into lymphoplasmacytic sclerosing pancreatitis (LPSP) and IDCP. Then, clinicopathological characteristics were compared between LPSP and IDCP.
RESULTS
Fourteen cases (36.8%) were IDCP. IDCP affected younger patients more than LPSP. IDCP was associated with ulcerative colitis in 35.7% of cases, whereas LPSP was associated with IgG4-related sclerosing diseases such as cholangitis, retroperitoneal fibrosis or sialadenitis in 41.7% of cases. IDCP was microscopically characterized by neutrophilic ductoacinitis with occasional granulocytic epithelial lesions, whereas LPSP was characterized by storiform inflammatory cell-rich fibrosis and obliterative phlebitis. IgG4-positive cells were not detected in any IDCP case but more than 20 IgG4-positive cells per high-power-field were invariably detected in LPSP cases. All patients with IDCP responded dramatically to steroids without recurrence, whereas 33.3% of patients with LPSP developed recurrences.
CONCLUSIONS
IDCP is clinicopathologically distinct from LPSP and can be diagnosed when neutrophilic ductoacinitis or granulocytic epithelial lesions are observed in a pancreatic biopsy under the appropriate clinical setting.

Abstract PDF

BACKGROUND
The grey zone of cervical cytology, and in particular atypical squamous cells, cannot exclude HSIL (ASC-H) causes diagnostic difficulties and increases medical expenses. We analyzed p16INK4a expression in ASC-H liquid-based cytology specimens (LBCS) to develop more effective methods for the management of ASC-H patients.
METHODS
We carried out p16INK4a immunostaining with 57 LBCS of ASC-H diagnostic categories, all of which were histologically cofirmed and 43 cases of which were compared with the results of a human papillomavirus (HPV) chip test.
RESULTS
p16INK4a immunostaining with ASC-H LBCS was positive in 20% (3/15) of cervicitis, 25.0% (3/12) of tissue-low-grade squamous intraepithelial lesion, 75.0% (18/24) of tissue-high grade squamous intraepithelial lesion (HSIL), and 100% (6/6) of invasive cancer cases. The positivity of p16INK4a in LBCS was correlated with higher grade of histologic diagnosis (r=0.578, p=0.000). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of p16INK4a immunostaining for the prediction of tissue-HSIL+ were 80.0%, 77.8%, 80.0%, and 77.8%, respectively. The sensitivity, specificity, PPV, and NPV of p16INK4a immunostaining plus HPV chip test for predicting tissue-HSIL+ were 71.2%, 86.4%, 84.2%, and 79.2%.
CONCLUSIONS
p16INK4a immunostaining as well as HPV chip testing with remaining LBCS with ASC-H are useful objective markers for the prediction of tissue-HSIL+.

Abstract PDF

BACKGROUND
We examined cervicovaginal smears that contained definite low-grade squamous intraepithelial lesion (LSIL) cells and rare atypical cells suggestive of high-grade SIL (HSIL) (ASC-H) or contained borderline dysplastic cells between LSIL and HSIL. Such lesions were classified as LSIL-H. This study aimed to investigate the cytologic and histologic characteristics of LSIL-H category and we evaluated the associated clinical risk.
METHODS
The histologic outcomes of LSIL-H were compared with those of LSIL and ASC-H. Both the cytologic and histologic findings of LSIL-H that were confirmed as cervical intraepithelial neoplasia 2 (CIN2) or greater (CIN2+) were investigated.
RESULTS
LSIL-H accounted for 0.09% of the Pap tests. On the follow-up histology, the most frequent outcome was CIN2, and the risk of CIN2+ was higher than that for ASC-H. In the cases of LSIL-H that was histologically confirmed as CIN2+, most of the atypical cells suggestive of HSIL were cytologically similar to those of CIN2, and the corresponding cervical tissues were characterized by small CIN2+ lesions in a large background of flat condyloma/CIN1. The LSIL-H cases not confirmed on initial colposcopically-directed biopsy required further follow-up.
CONCLUSIONS
LSIL-H may be a valid diagnostic category with distinctive features that are different from LSIL or ASC-H. LSIL-H needs further follow-up for the proper management.

Abstract PDF

BACKGROUND
The epithelial mesenchymal transition (EMT) is intimately associated with tumor hypoxia. The present study was conducted to investigate the immunohistochemical relationship between hypoxic and EMT-related molecules in non-small cell lung carcinoma (NSCLC).
METHODS
Immunohistochemical staining for hypoxia inducible factor (HIF)-1alpha, carbonic anhydrase (CA) IX, TWIST, and E-cadherin proteins was performed in 146 cases of NSCLC (80 cases of adenocarcinoma and 66 cases of squamous cell carcinoma) using tissue microarray blocks.
RESULTS
HIF-1alpha, TWIST, CA IX, and E-cadherin were expressed in 58 (40%), 90 (62%), 82 (56%), and 36 (25%) of 146 NSCLC cases, respectively. TWIST expression was positively correlated with HIF-1alpha expression (p = 0.03) and inversely correlated with E-cadherin expression (p < 0.01). TWIST and CA IX expression were not significantly interrelated, but each showed a relationship with histological tumor grade. However, the expression of these molecules had no significant effect on clinical staging or patient survival.
CONCLUSIONS
Although TWIST expression was correlated positively with HIF-1alpha expression and inversely correlated with E-cadherin, HIF-1alpha expression was not associated with E-cadherin expression. However, considering the relationship between HIF-1alpha and TWIST expression, further studies should be performed to demonstrate the role of hypoxia-induced EMT in NSCLC.

Abstract PDF: Epithelial-myoepithelial carcinoma (EMC) is a rare low grade malignant tumor of the salivary glands and it shows a characteristic biphasic population of epithelium and myoepithelium. It shows various cytologic and histologic features, so making an exact diagnosis is difficult. We report here on two cases of epithelial-myoepithelial carcinoma arising from the parotid gland and we compare the cytologic findings of the aspirated samples with the histologic findings of the tumors. We think the finding of mixed pattern of large, clear myoepithelia and small epithelia is the most valuable finding in the diagnosis of EMC.

Abstract PDF: Epithelial-myoepithelial carcinoma (EMC) is a low grade malignant neoplasm that commonly occurs in the parotid gland. Recently, we investigated a case of EMC that occurred in the external auditory canal (EAC) in a 35-year-old male, and this tumor was initially diagnosed as pleomorphic adenoma. The difficulty associated with diagnosing EMC by aspiration cytology arises from both the rare incidence of this tumor and the overlapping spectrum of cytological features found in various salivary gland tumors, such as pleomorphic adenoma, basal cell adenoma and adenoid cystic carcinoma.

Abstract PDF: It has suggested that a significant proportion of intraepithelial lesion of the cervix may be related to the influence of human papillomaviurs (HPV). Its etiological relation with cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma has recently been proposed. The 131 cases of CIN and 6 condyloma acuminata were stained by immunoperoxidase technique for HPV anigen. The results are as follows: The 18 cases (13.1%) exhibited positive staining, localized in nuclei of koilocytotic cells confined to superficial and intermediate layer of epithelium. HPV antigen was found in 1 case (16.7) of 6 condyloma acuminata, 4 cases (12.5%) of 32 mild dysplasia, 3 cases (13.6%) of 22 moderate dysplasia, 2 cases (14.3%) of 14 severe dysplasia and 8 cases (12.7%) of 63 carcinoma in situ. In the positive cases of mild and moderate dysplasia, HPV antigen was localized directly within the lesion, while those cases of severe dysplaia and carcinoma in situ contained positive cells in areas of mild or moderate dysplasia adjacent to the lesion. Of three distinct morphologic patterns, flat type was most common and papillary type was least. Histologically condylomatous lesions were present in 67 cases (51.1%) out of 131 cases of CIN. The histological and cytological feature encountered most frequently was koilocytotic arypia. Other main histological features are bi- or multinucleation, exocytosis of inflammatory cells, acanthosis, mitotic figures, dyskeratosis and epithelial pearl. On the cervical smear, the evidence of condyloma was proved in 50.0%. Cytologically in the condyloma with high degree of CIN, the nuclear atypia was so prominent that the differentiation from dysplasia or carcinoma in situ was very difficult, although the chromatin appeared somewhat smudged. The mean age of 18 cases was 42.4 years which is older than previous study. The results of this study provide common association with HPV and CIN and add great weight to the suggestion that the infection with HPV plays an important part in genesis of cervical cancer.

Abstract PDF: Odontogenic gingival epithelial hamartoma (OGEH) is an extremely rare lesion characterized by an abnormal proliferation of odontogenic epithelium. This lesion is thought to arise from the rest of the dental lamina lying dormant in the gingival tissue after odontogenesis. Distinguishing OGEH from the granular cell variant of ameloblastoma and central odontogenic fibroma is important. To date, only eleven cases have been reported, and its pathogenesis remains unclear. We report here on a case of OGEH, where the epithelial strands in the lesion were conspicuously positive for the antisera of cytokeratin 19 and ameloblastin. Tumor cells intensely expressed ameloblastin mRNA by in situ hybridization. To the best of our knowledge, this is the first case of OGEH to which ameloblastin immunohistochemical stain and in situ hybridization were applied. Although our study is limited to a single case, the coexpression of cytokeratin 19 and ameloblastin might indicate the origin and specific cytodifferentiation of OGEH is quite different and unique, when contrasted to other odontogenic tumors.

Abstract PDF: Pathogenetic mechanisms of progressive glomerulosclerosis are not clear. We studied the long-term(10 weeks) effects of puromycin aminonucleoside(PAN) in Sprague-Dawley rats with or without uninephrectomy(UN). Compared to rats with PAN injections only, rats with uninephrectomy and PAN injections showed significantly higher serum levels of urea nitrogen(153 +/- 155 mg/dl vs. 16 +/- 4 mg/dl, p<0.01), ceatinine(2.96 +/- 1.21 mg/dl vs. 0.92 +/- 0.36 mg/dl, p<0.01), cholesterol(466 +/- 125 mg/dl vs. 94 +/- 27 mg/dl, p<0.01), and triglyceride(337 +/- 237 mg/dl vs. 111 +/- 36 mg/dl, p<0.05) as well as increased amounts of proteinuria(428 +/- 90 mg/day vs. 136 +/- 130 mg/day, p<0.01). Lesions of focal segmental glomerulosclerosis(FSGS) were more frequently observed in rats with UN and PAN injections than rats with PAN infections only(39.5 +/- 17.2% vs. 4.3 +/- 4.7%, p<0.01). Ultrastructural examination of the glomeruli from rats with UN and PAN injections revealed severe epithelial cell changes including foot process effacement, vaculoar change or pseudocyst formation and focal detachment of epithelial cells from the underlying basement membrane. The results suggest that chronic nephrosis induced by PAN showed functional and morphologic features similar to those of human FSGS. Cytotoxic effect of PAN on the glomerular epithelial cells may be an initiating factor for the development of FSGS. which may be aggravated by some hemodynamic changes induced by uninephrectomy.

Abstract PDF: Secretory meningioma is now a distinctive subtype of mostly meningotheliomatous type of meningioma, which was first defined by Alguacil-Garcia et al. It shows characteristic light-microscopic, ultrastructural, and immunohistochemical features of epithelial and secretory differentiation of meningothelial cells with accumulation of secretory material in the from of hyaline inclusions. A 38-year-old female presented with headache for about 5 months. Magnetic resonance imaging revealed a round multilobated mass, measuring 4x4x3 cm, in the right inferior frontal lobe near the skull base, with surrounding brain edema. Histologically, the tumor basically showed a pattern of meningotheliomatous meningioma but tended to deposit eosinophilic homogeneous material both in the intracellular and extracellular spaces. The shape was globular intracellularly and of variable shape and often conglomerated extracellularly. Histochemical stains revealed the material not of psammomatous but of pseudopsammomatous proteinaceous nature. On electron microscopy, there was no intracellular lumen with secretion but granular electron-dense material of variable size accumulated in the degenerated endoplasmic reticulums, suggestive of proteinaceous secretion.

Abstract PDF: To evaluate the relationship between the expression of CA 125, CA 19-9, and CA 15-3 and ovarian epithelial tumors, immunohistochemical stainings were performed and analyzed to the types of tumor, and the degree o malignancy and differentiation in the total 42 cases. The results were summarized as follows: 1) The expression of CA 19-9 and CA 15-3 was demonstrated in most cases of benign, borderline and malignant mucinous tumors. All types tumors were negative for CA 125. 2) All types of serous tumors including benign, borderline and malignant revealed strong positive reaction for CA 125 and CA 15-3 in contrast to some weak positivity for CA 19-9. Expression of CA 125 was significantly increased in high grade serous adenocarcinomas compared with low of grade. 3) Endometrioid carcinomas revealed strong positive reaction for CA 15-3 in contrast to some positivity for CA 125 and CA 19-9. One case of Brenner tumor expressed CA 19-9 and CA 15-3 without expression of CA 125. 4) Serum CA 125 levels were elevated in 80% and CA 15-3 levels in 100% of ovarian epithelial malignancy. The correlation between serum levels and staining intensities was moderate.

Abstract PDF: BACKGROUND
p27kip1 is a member of the Cip/Kip family of the cyclin-dependent kinase inhibitors and is a potential tumor suppressor gene. Decreased expression of p27kip1 is associated with high histologic grade and poor prognosis in a variety of human tumors.
METHODS
Sixty-six cases of serous epithelial ovarian tumors were investigated by immunohistochemical staining for p27kip1, cyclin D1, and Ki-67. Clinicopathologic parameters (WHO classification, histologic grade and FIGO stage) were compared with the incidence of p27kip1, cyclin D1 and Ki-67 protein expression in ovarian serous tumors.
RESULTS
Reduced expression of p27kip1 was found more freguently in serous cystadenocarcinoma than in serous cystadenoma and borderline malignancy (p<0.05). The decreased expression of p27kip1 was correlated with a high histologic grade and an advanced FIGO stage. Overexpression of cyclin D1 is associated with borderline malignancy and grade I serous cystadenocarcinoma. An inverse relationship was observed between the p27kip1 protein and the Ki-67 labeling index within serous cystadenocarcinoma, but it was not significant.
CONCLUSIONS
Reduced expression of p27kip1 protein plays an important role in the biologically aggressive behavior of serous epithelial ovarian tumors and might represent a useful prognostic marker for predicting the recurrence in primary ovarian tumors.

Abstract PDF: The assessment of epithelial changes in gastric mucosal biopsies has been one of the major problems caused by inconsistencies in and disagreements about nomenclature and interpretation. To resolve these issues, members of the Study Group for Pathology of Digestive Diseases reviewed microslides of 50 gastric lesions showing varying degrees of mucosal abnormality and reached the following consensus; 1) the proliferating gastric epithelium can be divided into hyperplastic and neoplastic; 2) the term "dysplasia" is reserved for the microscopic epithelial changes that are unequivocally neoplastic; 3) Biopsy specimens can be categorized as regenerative(negative for dysplasia), indefinite(questionable dysplasia), positive(positive for dysplasia) and overt carcinoma; 4) The positive category can be divided into two subgroups, high grade dysplasia and low grade dysplasia. Criteria for each grade are presented and discussed. We offer these guidelines for establishing the correct diagnosis of the gastric mucosal biopsy specimens and for prospective studies.

Abstract PDF: Epithelial-myoepithelial carcinoma is an uncommon, low grade malignant epithelial neoplasm and metastasis is exceedingly rare. This article highlights the fine needle aspiration cytology(FNAC) of a case of metastatic epithelial-myoepithelial carcinoma of the scalp. A 51-year-old female presented with the left parietotemporal scalp mass two months after the left parotidectomy for epithelial-myoepithelial carcinoma. FNAC from the scalp mass showed a biphasic population of ductal epithelial and myoepithelial origin. These epithelial aggregates were numerous and formed a distinct three dimensional architecture in the background of numerous naked nuclei. The three dimensional architectures were predominantly composed of tightly cohesive eosinophilic ductular epithelial cells which tended to aggregate, overlap, and form tubules. Clear myoepithelial cells in three dimensional tissue fragment were inapparent and a few were attached to the periphery of the fragments. A few myoepithelial cells with clear abundant vaculoated cytoplasm were found in the foamy background. The cytological diagnosis was metastatic epithelial-myoepithelial carcinoma. The histologic findings of the scalp mass were those of typical epithelial-myoepithelial carcinoma. Cytologic distinction of epithelial-myoepithleial carcinoma, pleomorphic adenoma, and adenoid cystic carcinoma may be very difficult but careful attention to clinical features and cellualr details can classify these neoplasms correctly.

Abstract PDF: The authors report a case of malignant teratoma in a 3-year-old girl who suffered from occipital headache and vomiting for about 2 months. The tumor occupied left cerebellopontine angle resulting in a moderate degree of hydorcephalus. Histologically, the tumor consisted mainly of neuroepithelial tissues showing varying degrees of differentiation, with areas of epidermis, mature fat tissue, connective tissue, gastrointestinal glands and smooth muscle bundles containing ganglions. Also noted are groups pf polygonal or spindle cells representing immature mesodermal tissue. In contrast to two malignant intracranial teratomas previously reported in Korean literatures, this case is characterized by the presence of predominent neuroepithelial components and by uncommon tumor location, the posterior fossa far from middle line of the body.

Abstract PDF: Immunohistochemical stains for bcl-2 oncoprotein and PCNA and examination of the mitosis level were perfon-ned in 76 cases of cervical intraepithelial neoplasia (CIN). We studied the expression pattern of bcl-2 protein according to histologic grades and the function of bcl-2 oncogene associated with cellular proliferation by comparing with PCNA expression and the mitosis level. The results were as follows: 1) Of 76 cervical intraepithelial neoplasias, 23 (30.3%) were CIN I, 23 (30.3%) were CIN II, and 30 (39.4%) were CIN III. 2) Of 23 CIN I cases, grade 0 and 1 mitosis level were seen in 20 (87.0%), PCNA in 16 (69.6%), and bcl-2 in 19 (82.6%) cases, respectively, which indicates that CIN I lesions have a low cellular proliferative activity. 3) Of 30 CIN III cases, grade 2 and 3 mitosis level were noted in 28 (93.3%), PCNA in 25 (83.3%) and bcl-2 in 19 (63.3%) cases, respectively, which indicates that CIN III lesions have a high cellular proliferative activity. The results suggest that progressive increase of dysfunctional proliferative activity and abnormal decrease of cell death result in increased number of neoplastic cells according to CIN grade. Also the expression rate of bcl-2, PCNA and mitosis level were significantly different between CIN I and 111, which suggest that they might be good parameters for classifying CIN into low and high grade and for prediction of the biologic behavior of the CIN lesion.

Abstract PDF: Cervical intraepithelial neoplasia in human consist of dysplasia of various developmental stages and squamous cell carcinoma in situ of various types. These lesions can be diagnosed cytologically on cervico-vaginal smears, although the diagnostic reproducibility is limited. To obtain the objects morphologic distinction between normal squamous epithelial cell in different maturation, different stages of dysplastic cells and varieties of in situ carcinoma cells, Kontron IBAS-1 imaging analyzer was applied for the measurement of nuclear and cytoplasmic areas of each categorised cells. The followings are results obtained: 1) Nuclear and cytoplasmic areas of superfical (36.9 micrometer2, 2319.9 micrometer2) intermedicate (45.7 micrometer2, 2989.7 micrometer2) and parabasal cells (50.8 micrometer2, 432.7 micrometer2) of normal squamous epithelium origin are mostly distinctive between cell types. However, cytoplasmic areas of both superficial and intermediate cells and nuclear areas of both intermediate and parabasal cells are not significantly different. 2) Normal squamous cells and various dysplastic cells show obvious difference in their nuclear and cytoplasmic areas, while difference between cytoplasmic areas of both parabasal (432.7 micrometer2) and severe dysplastic cells (409.7 micrometer2) are not statistically significant. 3) No statistical difference is observed in between nuclear areas of both moderate dysplastic (112.3 micrometer2) and severe dysplastic cell (117.6 micrometer2). 4) Varieties of carcinoma in situ cells and severe dysplastic cells are in difference in their nuclear and cytoplastic areas, whereas nuclear areas from both in situ carcinoma cells (95.3 micrometer2) of large cell type and severe dysplasia (117.6 micrometer2) are not distinctive. The results lead the author to consider that the morphometric analysis for various parameters of cell constituents are of value in making objective distinction between cells from cervical intraepithelial neoplasia in human.

Abstract PDF: Cysts of the iris may be primary lesions of either epithelial or stromal in origin, or secondary lesions after trauma or surgery. The stromal cyst is usually of primary lesion, although it could be secondary as shown in our case. We report a case of recurrent iris cyst after trauma. The patient was an 8-year-old girl. She had a penetrating injury of the involved eye three years ago. She had a similar iris cyst removed two years before this surgery. Histologically, the cyst was lined by non-keratinizing stratified squamous epithelia and subjacent fibrovascular tissue. Islands of melanin-containing epithelial cells and acellular basophilic degenerating materials were also seen in the lesion. This case represents a stromal epithelial cyst that by history appears to be of post-traumatic etiology.

Cytologic fieatures of ASCUS, R/O HSIL included atypical single small cells(36.6%), hyperchromatic tissue fragments(35.6%), atypical metaplastic cells(18.8%), endometrial cell-like clusters(5.9%), and atypical parakeratotic cells(3.0%). A final diagnosis of HSIL on biopsy was assigned to 47(54.0%) of 87 women with ASCUS, R/O HSIL and to 13(14.6%) of 89 women with ASCUS, NOS ( p=0.000). There was no difference in HPV DNA detection rate between ASCUS, R/O HSIL and ASCUS, NOS smears. These data suggest that subclassification of ASCUS is helpful to manage patients because ASCUS, R/O HSIL is more often associated with an underlying HSIL on biopsy. Therefore, women with ASCUS, rule out HSIL should be actively managed with colposcopic examination.

Abstract PDF: Papillary immature metaplasia (PIM) of the uterine cervix (immature condyloma) is a subset of low grade squamous intraepithelial lesion (LSIL) which is frequently associated with human papilloma virus (HPV) types 6 and 11. The histologic features of PIM include filiform papillae lined by evenly spaced immature metaplastic-type cells with frequent nucleoli, mild anisokaryosis, and a low mitotic index. To characterize the cytologic changes associated with PIM, we analyzed 14 cases of PIM from our file. We reviewed biopsy slides and the cervicovaginal smears taken proximate to the time of biopsy. Histologically, nine cases had either flat condyloma (7 cases) or high grade squamous intraepithelial lesion (HSIL) (2 cases). Cytologic changes included cells in various stages of maturation with karyomegaly (14 cases), cells with irregularities in the nuclear membrane (13 cases), intermediate cells with karyomegaly(13 cases), cells with binucleation (13 cases), and aborted koilocytes (11 cases). Cervicovaginal smears from all cases were interpreted as atypical squamous cells of undetermined significance (ASCUS), NOS or ASCUS, rule out squamous intraepithelial lesion (SIL) or LSIL in two cases with flat condyloma or HSIL in a case with severe dysplasia. PIM is a distinct histologic entity that can present with a spectrum of cytologic findings, but cytologic findings may resemble variable reactive conditions and immature HSIL. Therefore, it is difficult to diagnose PIM by cytology alone. However, the meticulous efforts for making the cytologic diagnoses which can induce active management of patients are recommended because PIM is a variant of LSIL and frequently has a flat condyloma or HSIL.

Abstract PDF: The lymphoepithelial cyst (LEC) rarely occurs in the thyroid gland. The LEC has been thought to be related to developmental rest, namely solid cell nest, which is derived from ultimobranchial body. We report a case of lymphoepithial cyst in a 34- year-old woman clinically diagnosed with Hashimoto's thyroiditis. The cyst was located in mid to lower portion of the left lobe. It was a single unilocular cyst, which for the most part was lined with squamous epithelium, and at certain foci with ciliated columnar epithelium. The cyst wall showed a dense lymphocytic infiltration, numerous lymphoid follicles with germinal centers and admixed thyroid follicles. This morphology is similar to the branchial cleft cyst, with the exception of the thyroid follicles in the cyst wall. Near the cyst were several solid epidermoid cell nests. Immunohistochemical stain of this cyst-lining epithelium and solid cell nests showed CEA positivity. In view of the similarity in histomorphology and CEA positivity to branchial cleft cyst of the lateral neck, the LEC of the thyroid could also have been of branchial origin. However, the admixed thyroid follicles in the cyst wall suggests that the LEC of the thyroid gland might have derived from another branchial cleft as a ultimobranchial body, because it has the potential for thyroid follicular differentiation.

Abstract PDF: The author examined expression of tumor-related antigens, such as p53 tumor supressor protein, c-myc, TGF-alpha, and TGF-beta proteins in 75 cases of surgically resected epithelial ovarian tumors. Peroxidase immunohistochemistry was used to determine the frequency of expression, the relationship among expression of these antigens and histopathological spectrums, and clinical stage, and their potential prognostic significance. The results are summarized as follows. A positive correlation was found between expression of p53(P=0.02), c-myc(P=0.03), and TGF-alpha(P=0.001) and histological degrees of malignancy(benign, borderline, or malignant) in epithelial ovarian tumors. A significant correlation was found between expression of p53 and histological degrees of malignancy in serous ovarian tumors(P=0.003) and mucinous tumors (P=0.049). A significant correlation was also found between expression of c-myc and the histological grade of serous carcinomas(P=0.02). A correlation between expression of these antigenic proteins and clinical stage of epithelial ovarian tumors was not demonstrated. Expression of p53 and c-myc was closely correlated with expression of TGF-alpha irrespective of the histological degrees of malignancy and type of epithelial ovarian tumors(0.4 < or = K < or = 0.7). The results of this study support the ideas that expression of c-myc and TGF-alpha might be a useful prognostic indicator in human ovarian carcinomas, and expression of p53 could be another indicator of prognosis, as the expression of p53 is characteristic in that the expression is mostly seen in invasive ovarian carcinomas.

Abstract PDF: Epithelial-myoepithelial carcinoma(EMC) is a rare, low grade malignant tumor of the salivary glands. The EMC has a distinctive histological appearance comprising ductal structures with an inner epithelial cell component and an outer layer of myoepithelial cells which show plump clear cytoplasm. The cytologic features of the EMC have been rarely described. A correct cytological diagnosis to this rare tumor is difficult with high false negative rate. We report a case of EMC in which fine needle aspiration cytologic findings were misinterpreted as a pleomorphic adenoma.

Abstract PDF: Lymphoepithelial carcinoma, also known as malignant lymphoepithelial lesion or lymphoepithelioma, is a rare tumor in salivary glands. Lymphoepithelial carcinoma has a characteristic histological findings comprising irregularly-shaped nests of malignant epithelial cells within a lymphocyte-rich stroma, occasionally forming lymphoid follicles. We recently experienced a case of fine needle aspiration cytology(FNAC) of lymphoepithelial carcinoma of parotid gland in a 61-year-old male. The FNAC yielded a hypercellular smear of many irregular clusters of malignant epithelial cells in the background of lymphoid stroma.

Abstract PDF: Peutz-Jeghers syndrome is an autosomal dominant disease characterized by gastrointestinal ployposis and mucocutaneous melanin pigmentation involving the lip, oral mucosa, digits, palms and soles. The polyps are almost hamartomatous. The relationship of gastrointestinal carcinoma and the Peutz-Jeghers syndrome has been discussed for many years. The question is unsettled whether gastrointestinal carcinoma arise in hamartomatous polyps itself. Recently, there are a few reports that adenomatous and carcinomatous changes were superimposed upon the background of the hamartoma. Occasionally epithelial misplacement of the epithelium is found in the small intestinal polyps. Since the epithelial misplacement may involve submucosa, muscularis propria and serosa, a difficulty of histopathologic differential diagnosis between the epithelial misplacement and invasive adenocarcinoma cause overdiagnosis of cancer in the gastrointestinal polyps of Peutz-Jeghers syndrome. We present a case of Peutz-Jeghers syndrome of 39-year-old woman with multiple gastrointestinal polyps, two of which showed extensive epithelial misplacement even into the pancreas and another one at the colon showed carcinomatous change at the tip portion. Areas of hamartoma, adenoma and in situ carcinoma were noted in this colonic hamartomatous polyp. This case support that adenoma and carcinomatous changes may evolve directly within a hamartomaous polyp itself.

Abstract: This study was undertaken to know the extent of apoptosis, expression of bcl-2 and proliferating cell nuclear antigen (PCNA) in uterine cervical intraepithelial neoplasia (CIN; 15 cases) and invasive carcinoma (27 cases) and to evaluate them as a prognostic marker. Apoptosis was analysed by using the in situ apoptosis detection kit and bcl-2 and PCNA were detected by the immunohistochemical method. The results were as follows: Apoptotic indices (AI) in the invasive carcinoma (mean: 4.3) were 10-times higher than that in the CIN (mean: 0.43). Bcl-2 was expressed 60% of the cases in the dysplastic cells of the CIN II and CIN III, 33.3% of cases in the invasive carcinoma and not expressed in the CIN I except basal cells. The expression of the PCNA was increased by the grades of CIN and was strong in invasive carcinoma. The mean survival time of the patient with invasive carcinoma was significantly decreased in the higher AI index (above 4.3) than in the lower AI index (below 4.3). There was no significant correlation between the extent of apoptosis and the expression of bcl-2. According to the above results, AI are able to be used as an independent prognostic marker in the invasive cervical carcinoma, and bcl-2 and PCNA have an important role in the tumorigenesis of uterine cervical carcinoma.

Abstract: Synovial sarcoma is a rare soft tissue tumor accounting for 5-10% of soft tissue sarcomas. Most arise in the extremities and trunk, and a small proportion occur in the abdominal wall, head and neck region, and mediastinum. It manifests different phenotypic subtypes that render their cytologic evaluation challenging. Moreover, cytomorphologic description of the epithelial component of synovial sarcoma is rare in Korea. We report a case of biphasic synovial sarcoma on the right lower extremity in a 49-year-old woman diagnosed by fine needle aspiration cytology. The aspirate was moderately cellular and composed of a mixture of tissue fragments and dissociated cells with bland chromatin, inconspicuous nucleoli, and oval to spindle-shaped cytoplasm. Mitosis was rare. A monolayer sheet of epithelial component was seen. The cells in this monolayer sheet had more abundant distinct cytoplasm, round nuclei, and prominent micronucleoli. Histologic examination showed a biphasic pattern consisting of mostly sarcomatous stroma and a few small glandular areas at the periphery of the tumor.

Abstract PDF: Papillary and solid epithelial neoplasm is a rare pancreatic tumor of low-grade malignancy. We report a case of a 23 year old female having solid and papillary neoplasm of the pancreatic tail with mutiple omental and peritoneal metastases. Microscopically, the main tumor showed typical histologic findings including solid and papillary areas with cystic change. But the metastasizing nodules were largely solid and the tumor cells demonstrated increased nuclear pleomorphism, hyperchromasia and an increased mitotic rate. The tumor cells contained considerable amount of intracellular and extracellular eosinophilic inclusions which were ultrastructually zymogen-like granules. These inclusions were more frequently found in the metastatic nodules. By flow cytometric study, the tumor was hyperdiploid. The DNA index was not significant.

Abstract PDF: Prostatic carcinoma is the most commonly diagnosed cancer in the United States in men. Prostatic carcinoma in Korean men is uncommon and accounts for less than 1% of total cancer: however, the incidence of prostatic carcinoma is continuously increasing. Several clinicopathologic parameters including stage, Gleason score, and serum PSA level have been widely accepted as well established prognostic factors. To study the clinicopathologic features of prostatic carcinoma in Korean men, 58 cases of prostatic carcinoma, which were diagnosed on radical prostatectony specimens at Asan Medical Center from Jan. 1993 to June 1998 (1993; 3 cases, 1994; 3, 1995; 6, 1996; 12, 1997; 24, 1998; 10), were evaluated. The prostatic carcinomas were divided into three groups according to Gleason score. Tumors with Gleason score 6 or lower, 7, and 8 to 10 were categorized as low-grade, intermediate-grade and high-grade tumor, respectively. The overall mean age of the patients was 62.6 years (range, 4 6~76 years); mean age was 65.4, 62.8 and 61.1 in low, intermediate and high-grade tumor, respectively (p>0.05). The overall mean serum PSA level was 38.6 ng/ml (range, 0.3~276.0 ng/ml); mean serum PSA level was 17.0, 29.0 and 60.9 ng/ml in low, intermediate and high-grade tumor, respectively (p=0.002). The mean T stage was 2.3, 2.4 and 3.1 in low, intermediate and high-grade tumor (p=0.001). The percentage of positive resection margin was 33.3, 50.0 and 91.0 % in low, intermediate and high-grade tumor (p=0.001). The overall presence of prostatic intraepithelial neoplasia (PIN) was 79.3 %; percentage of the presence of PIN was 100, 79.2 and 68.2 % in low, intermediate and high-grade tumor (p>0.05). As reported in the literature, our results indicated that Gleason score was a good predictor of stage and prognosis. The higher Gleason score, the more cases were with positive surgical margins, advanced pathologic stage, and high serum PSA level (p<0.05).
