AbstractAbstract PDF

Uterine rhabdomyosarcoma (RMS) typically presents as a mixed epithelial and mesenchymal tumors. Pure RMSs of the female genital tract are uncommon. Spindle cell variant of RMS is a rare morphologic subtype of embryonal RMS and mostly occurs in the paratesticular region of children. Here, we present a case of uterine spindle cell RMS in a 76-year-old woman. The tumor, 20×15×7 cm in size, was highly necrotic and adherent to the colon and rectum. Tumor cells were mostly spindle-shaped, and isolated rhabdomyoblasts were scattered. Immunohistochemical stains for myoglobin and myo-D1 showed diffuse positivity for tumor cells. The patient died only of disease three months after diagnosis.

AbstractAbstract PDF
Background

The incidence of early colorectal epithelial neoplasm (ECEN) is increasing, and its pathologic diagnosis is important for patient care. We investigated the incidence of ECEN and the current status of its pathologic diagnosis.

Methods

We collected datasheets from 25 institutes in Korea for the incidence of colorectal adenoma with high grade dysplasia (HGD) and low grade dysplasia in years 2005, 2007, and 2009; and early colorectal carcinoma in the year 2009. We also surveyed the diagnostic terminology of ECEN currently used by the participating pathologists.

Results

The average percentage of diagnoses of adenoma HGD was 7.0%, 5.0%, and 3.4% in years 2005, 2007, and 2009, respectively. The range of incidence rates of adenoma HGD across the participating institutes has gradually narrowed over the years 2005 to 2009. The incidence rate of early colorectal carcinoma in the year 2009 was 21.2%. The participants did not share a single criterion or terminology for the diagnosis of adenoma HGD. The majority accepted the diagnostic terms that distinguished noninvasive, mucosal confined, and submucosal invasive carcinoma.

Conclusions

Further research requirements suggested are a diagnostic consensus for the histopathologic diagnosis of ECEN; and standardization of diagnostic terminology critical for determining the disease code.

AbstractAbstract PDF
BACKGROUND
Annexin A1 (ANXA1) is known to be involved in the progression and differentiation of various tumors. However, its significance and role in bladder carcinogenesis has not been fully elucidated. To determine the role ANXA1 plays in urothelial carcinoma (UC), we investigated the expression of ANXA1 protein in normal urothelial tissue, carcinoma in situ (CIS), and UC of the urinary bladder.
METHODS
Protein expression level of ANXA1 and its subcellular localization were analyzed in 88 cases of UCs and corresponding 24 normal tissues and 24 CISs by immunohistochemistry.
RESULTS
ANXA1 was significantly down-regulated at all subcellular localization in CIS and in the cytoplasm and membrane of cells of UC, compared to normal tissues. No significant correlation between ANXA1 expression level and tumor depth (pT), growth pattern, and recurrence was found. However, cytoplasmic and membranous ANXA1 were significantly up-regulated in high grade than in low grade UC (p=0.02 in cytoplasm and p=0.03 in membrane).
CONCLUSIONS
These results suggest that ANXA1 dysregulation is involved in urothelial carcinogenesis and ANXA1 is potentially a marker for the pathologic differentiation of UC.

AbstractAbstract PDF
BACKGROUND
To standardize renal biopsy reporting and diagnosis, The Renal Pathology Study Group of the Korean Society of Pathologists (RPSKSP) has developed a renal pathology reporting format for the native and allograft kidney.
METHODS
A consensus checklist of a provisional renal biopsy format was sent to all members of the RPSKSP. Feed back opinions regarding the practical application of the checklist to the diagnostic work were received.
RESULTS
Kidney biopsies require three essential examinations: by light microscopy, immunofluorescence (IF), and electron microscopy (EM). A final report of a renal biopsy should include information on specimen adequacy and a description of the morphologic change using a systematic semiquantitative method for each of the compartments, with optional separate IF and EM reports.
CONCLUSIONS
A standard renal biopsy report format is important in establishing clinicopathologic correlations, making reliable prognostic considerations, comparing the findings in sequential biopsies and evaluating the effects of therapy.

AbstractAbstract PDF
Enterobius vermicularis is one of the most common parasites found in the intestine of humans. The gravid female worms migrate outside the anus to release eggs on the perianal skin. Rarely, they migrate to the genitourinary tract in female patients. We present a case in which pinworm eggs were found in a cervicovaginal smear of a 37-year-old woman. The eggs were elongated oval shaped and flattened on one side. The thick, double contoured birefringent shell stained bright yellow or orange. Some coarsely granular embryos or curved larvae were enclosed in the refractile shell. Empty eggs or wrinkled shells with clumped granular material were also present. Although pinworm eggs are easily identified because of their characteristic morphologic appearance, careful screening is needed due to the frequent masking by inflammatory cells.

AbstractAbstract PDF
Estrogen and progesterone receptors exist in the epithelial and stromal cells of the endometrium. Proliferative disorders of the endometrium may be associated with autocrine and paracrine actions of estrogen and progesterone in epithelial and stromal cells. This study was performed to evaluate the differences estrogen and progesterone receptor(ER/PR) expression in the epithelial and stromal cells of endometrial hyperplasias and adenocarcinomas using immunohistochemical methods. Immunohistochemical analysis of proliferating cell nuclear antigen(PCNA) was done to evaluate a possible correlation between PCNA and hormone receptor expression. Evaluation was based on samples from 31 simple hyperplasias, 30 complex hyperplasias, and 32 adenocarcinomas. The immunohistochemical expression of ER, PR and PCNA in epithelial and stromal cells were examined according to a scoring system based on the percentage of positive cells and the staining intensity. The results were as follows; 1) The expression of ER and PR in epithelial cells showed a graded, significant decreases in simple hyperplasia, complex hyperplasia and endometrial carcinoma, in that order(ER: P=0.008, PR: P= 0.026). 2) PR expression in the stromal cells showed a significant decrease between hyperplasia and adenocarcinoma(P=0.003). The difference in ER expression was not significant. 3) In stromal cells, the decrease in PR expression was more prominent than the decrease in ER expression when complex hyperplasia was compared to simple hyperplasia. 4) The PCNA expression in simple and complex hyperplasia and adenocarcinoma was not higher than the expression of PCNA in nomal proliferative endometrium. There was no significant difference in PCNA expression between simple and complex hyperplasia and adenocarcinoma(P=0.073). 5) A negative correlation between PCNA and ER/PR expression was not demonstrated in simple and complex hyperplasia, or in adenocarcinoma. Endometrial hyperplasia and adenocarcinoma are probably related to a paracrine action of estrogen and progesterone in epithelial and stromal cells. A progressive loss of PR expression in stromal cells may induce abnormal proliferation of endometrium due to a disrupted hormonal balance.

AbstractAbstract PDF
Bcl-2 oncoprotein is being localized to mitochondria and interfering with programmed cell death (apoptosis) independent of promoting cell division in the lymphoid and nonlymphoid cells. The bcl-2 oncoprotein expression has been reported in follicular lymphomas as well as in diffuse non-Hodgkin's lymphoma, leukemia and a variable propotion of Hodgkin's lymphoma cases. Recent evidence suggests that some lymphomas protected from apoptosis is conferred through expression of Epstein-Barr virus(EBV) latent membrane protein which turn to cause upregulation of bcl-2. To define the role of the bcl-2 oncoprotein and EBV in lymphoid malignancy, we tried immunohistochemical studies with anti-bcl-2 antibody and In situ hybridization (ISH) with EBV-encoded small nuclear RNAs(EBER) in the paraffin embedded sections of 46 non-Hodgkin's lymphoma (NHL) cases and 20 Hodgkin's lymphoma (HL) cases. Bcl-2 oncoprotein expression was found in 37 of 46 cases (80%) of NHL with relatively strong cytoplasmic staining, and in 14 of 20 cases (70%) of HL with weak cytoplasmic staining in limited small numbers of RS, Hodgkin and lacunar cells. The widespread presence of bcl-2 oncogene in many different types of both NHL and HL supports that the extended cell survival through overexpression of bcl-2 gene protein may be a growth advantage of neoplastic lymphoid cells. In the ISH analysis for EBV, the presence of EBV was detected in 17 of 20 cases (85%) of HL, compared to 6 of 44 cases(13.6%) of NHL. It appears to be no direct correlation between overexpression of bcl-2 oncoprotein by neoplastic lymphoid cells and the presence of EBV in NHL but it seems to be a definite association between EBV and HL.

AbstractAbstract PDF
Aggressive angiomyxoma is a rare, locally aggressive tumor and occurs exclusively in the pelvic and perineal regions of women. But this tumor can occur in men, and the ratio of man to woman is about 1:6. We report a case of aggressive angiomyxoma of the scrotum in a 75-year-old man. The resected mass measured 23 21 10 cm and weighed 1,150 g, and was covered with thick but intact scrotal skin. The cut surface of the mass showed pale yellow to grayish white loose and edematous fibrous tissue with focal cystic degeneration. Microscopically, the mass was composed of loosely arranged bland-looking spindle or stellate cells and variable sized blood vessels with thickened and hyalinized wall. The spindle cells were strong positive for vimentin, focal, weak positive for desmin and smooth muscle actin but negative for S-100 protein. The spindle cells were also positive for estrogen and progesterone receptors.

AbstractAbstract PDF
We report a case of idiopathic hypertrophic spinal pachymeningitis in a 56-year-old woman who complained of a tingling sensation and progressive weakenss of both legs since 6 months prior, and then was unable to walk for 1 week. Magnetic resonance imaging showed a low signal intensity of dural and epidural mass in the T7-T11. The mass was concentrically compressing the spinal cord and extending to the paraspinal area through the intervertebral foramina. Total laminectomy from T7 to T12 and mass removal were done. The mass was composed of markedly thickened dura mater. Microscopic examination showed fibrous thickening with hyalinization and infiltration of chronic inflammatory cells, mainly lymphocytes. Idiopathic hypertrophic spinal pachymeningitis is a rare disease causing progressive paraparesis that can resemble other disorders associated with spinal compression.

AbstractAbstract PDF
Fine needle aspiration biopsy has been proved as a safe, accurate and cost-effective diagnostic modality in palpable breast lesions. Cytologically, fibrocystic disease can be classified into 3 categories as nonproliferative breast disease, proliferative breast disease without atypia, and proliferative breast disease with atypia. This terminology for the needle aspirates is compatible with that of diagnostic histopathology. Cytologic differentiation of nonproliferative disease from proliferative breast disease is important, since the risk of cancer development in cases of atypical hyperplasia is 4-5 times higher than that of general population. Twenty five needle aspirates of fibrocystic disease confirmed by subsequent histopathology were re-evaluated and classified into 3 categories depending on their architectural and nuclear features. In addition. these aspirates were scored according to the cytologic grading system, devised by Masood et al. and based on six cytologic criteria. Concordance rates between cytomorpholgic diagnosis and cytologic diagnosis using the cytologic criteria grading system and histologic diagnosis were 88% and 92%, respectively.

AbstractAbstract PDF
Fine needle aspiration cytologic findings in 14 cases of gynecomastia are described. General cytomorphologic features resemble those of fibrocystic disease in women than those of fibroadenoma. Among the cytologic parameters, three-dimensional structure of epithelial cell clusters, presence of micronucleoli and irregularities of nuclear size and shape are suggestive of epithelial proliferative activity. In addition, 4 cases are proliferative breast disease without atypia and 10 cases are nonproliferative breast disease depending on cytologic criteria grading system.

AbstractAbstract PDF
Langerhans' cell histiocytosis is a relatively rare disorder of children, characterized by abnormal proliferation of Langerhans' cells. It usually presents as multiple osteolytic lesion with lymphadenopathy or cutaneous manifestations. We experienced a case of Langerhans' cell histiocytosis involving bone and lymph node, diagnosed by fine needle aspiration cytology of the lymph node. The patient was a 10-year old girl with left inguinal lymphadenopathy. Fine needle aspiration cytology from the lymph node disclosed very cellular smear consisted of Langerhans' cells, eosinophils and lymphocytes. The Langerhans' cells had eccentric oval to reniform shape nuclei with grooving and abundant pale cytoplasm. The diagnosis was confirmed later by histologic study of bone lesion.

AbstractAbstract PDF
Scattered single cells or variable sized clusters of signet ring cells in the aspirated smears of breast lesions are almost exclusively associated with carcinoma. The signet ring cells are defined as those containing a prominent intracytoplasmic vacuole or amorphous cytoplasm diffusely dispersed with mucin. The primary signet ring cell carcinoma of the breast behaves more aggressively than carcinoma without signet ring cells. Therefore, it is very important to make a correct diagnosis of signet ring cell carcinoma. Fine needle aspiration cytology is useful for diagnosis of breast lesions including signet ring cell carcinoma. We report two cases, which showed mostly signet ring cells in the aspirated smears of the breast. One case consisted of numerous individual signet ring cells and variable sized cell clusters in rather mucoid background. The tumor cells had abundant amorphous cytoplasm filled with dispersed mucin or occasionally mucin vacuoles(PAS +) and eccentric nuclei. The resected mass revealed mucinous carcinoma. The other showed the cytologic findings of low cellularity, and small loosely cohesive signet ring cell clusters with mild nuclear pleomorphism. It was confirmed as lobular signet ring cell carcinoma in the resected tumor.

AbstractAbstract PDF
A patient with actinomyces infection of the submandibular soft tissue was diagnosed by fine needle aspiration cytology (FNAC). A 38-year-old woman presented with a right submandibular mass which slowly grew in size over one month. Clinically and radiologically, the lesion was considered as tuberculous lymphadenitis or cellulitis. The polymerase chain reaction for tuberculosis was done by aspirated specimen but the result was negative. The smears of aspiration cytology showed characteristic colonies(sulfur granules) of actinomyces in inflammatory background. After antibiotic therapy for eight months, the patient has been well, showing no detectable mass. This patient was simply and rapidly diagnosed by FNAC and can avoid unnecessary surgical biopsy.
