Background
The decrease in incidence of cervical dysplasia and carcinoma has not been as dramatic as expected with the development of improved research tools and test methods. The human papillomavirus (HPV) test alone has been suggested for screening in some countries. The National Cancer Screening Project in Korea has applied Papanicolaou smears (Pap smears) as the screening method for cervical dysplasia and carcinoma. We evaluated the value of Pap smear and HPV testing as diagnostic screening tools in a single institution.
Methods
Patients co-tested with HPV test and Pap smear simultaneously or within one month of each other were included in this study. Patients with only punch biopsy results were excluded because of sampling errors. A total of 999 cases were included, and the collected reports encompassed results of smear cytology, HPV subtypes, and histologic examinations.
Results
Sensitivity and specificity of detecting high-grade squamous intraepithelial lesion (HSIL) and squamous cell carcinoma (SCC) were higher for Pap smears than for HPV tests (sensitivity, 97.14%; specificity, 85.58% for Pap smears; sensitivity, 88.32%; specificity, 54.92% for HPV tests). HPV tests and Pap smears did not differ greatly in detection of low-grade squamous intraepithelial lesion (85.35% for HPV test, 80.31% for Pap smears). When atypical glandular cells were noted on Pap smears, the likelihood for histologic diagnosis of adenocarcinoma following Pap smear was higher than that of high-risk HPV test results (18.8 and 1.53, respectively).
Conclusions
Pap smears were more useful than HPV tests in the diagnosis of HSIL, SCC, and glandular lesions.

Abstract PDF

Background
Pathologic diagnosis of central nervous system (CNS) neoplasms is made by comparing light microscopic, immunohistochemical, and molecular cytogenetic findings with clinicoradiologic observations. Intraoperative frozen cytology smears can improve the diagnostic accuracy for CNS neoplasms. Here, we evaluate the diagnostic value of cytology in frozen diagnoses of CNS neoplasms.
Methods
Cases were selected from patients undergoing both frozen cytology and frozen sections. Diagnostic accuracy was evaluated.
Results
Four hundred and fifty-four cases were included in this retrospective single-center review study covering a span of 10 years. Five discrepant cases (1.1%) were found after excluding 53 deferred cases (31 cases of tentative diagnosis, 22 cases of inadequate frozen sampling). A total of 346 cases of complete concordance and 50 cases of partial concordance were classified as not discordant cases in the present study. Diagnostic accuracy of intraoperative frozen diagnosis was 87.2%, and the accuracy was 98.8% after excluding deferred cases. Discrepancies between frozen and permanent diagnoses (n = 5, 1.1%) were found in cases of nonrepresentative sampling (n = 2) and misinterpretation (n = 3). High concordance was observed more frequently in meningeal tumors (97/98, 99%), metastatic brain tumors (51/52, 98.1%), pituitary adenomas (86/89, 96.6%), schwannomas (45/47, 95.8%), high-grade astrocytic tumors (47/58, 81%), low grade astrocytic tumors (10/13, 76.9%), non-neoplastic lesions (23/36, 63.9%), in decreasing frequency.
Conclusions
Using intraoperative cytology and frozen sections of CNS tumors is a highly accurate diagnostic ancillary method, providing subtyping of CNS neoplasms, especially in frequently encountered entities.

Abstract PDF

Background
The cytopathic effects of cytomegalovirus (CMV) infection have been well described since the virus was first reported; however, the morphology of CMV infection has not been clearly studied. We examined the difference in detailed cytologic findings in bronchial washing cytology between liquid-based and conventionally prepared smears. Methods: Bronchial washing cytology was processed using either the conventional preparation (CP) or liquid-based preparation (LBP). Sixty-nine cells with typical cytopathic effects of CMV infection were detected on CP slides and 18 cells on LBP slides. Using the image analyzer, area, circumference, major axis, and minor axis of the cytoplasm, nucleus, and intranuclear inclusion were measured in singly scattered CMV-infected cells, and histiocytes were used as a control. Results: The mean cytoplasmic area of CMV-infected cells was 1.47 times larger than that of histiocytes in CP and 2.92 times larger in LBP (p<.05). The mean nuclear area of CMV-infected cells was 2.61 times larger than that of histiocytes in CP and 4.25 times larger in LBP (p<.05). The nucleus to cytoplasm ratio and intranuclear inclusion to cytoplasm ratio of the mean area, circumference, major axis, and minor axis in CP were larger than those in LBP (p<.05). Conclusions: The sizes of cytoplasm, nucleus, and intranuclear inclusion were larger in LBP than in CP, indicating that CMV-infected cells are easily detectable in LBP. However, the nucleus-to-cytoplasm ratio was larger in CP, suggesting that differentiation from malignancy or regenerative atypia requires caution in CP.

Abstract PDF

Background

Immunohistochemical staining for p16INK4a and Ki-67 has been used to improve the accuracy in making a diagnosis of the uterine cervix cancer on biopsy. This study was conducted to examine the usefulness of these markers in the pathological diagnosis based on cervical biopsy.

Methods

We selected a consecutive series of 111 colposcopically directed cervical punch biopsies. Using these biopsy samples, we performed an immunohistochemical staining for p16INK4a and Ki-67 to establish a diagnosis. The slides were circulated among four pathologists in a sequential order: the hematoxylin and eosin (H&E) slide, H&E slide and p16INK4a-stained slide, and H&E slide, p16INK4a- and Ki-67-stained slides.

Results

The overall rates of the concordance in the first, the second, and the third diagnoses were 77.5%, 82.0%, and 82.0%, respectively. The rate of the concordance in the diagnosis of cervical intraepithelial neoplasm (CIN) 2/3 was increased from 62.2% to 73.0%. But there was a variability in the rate of the revision of the diagnosis between the pathologists. With the application of criteria for interpreting the expressions of p16INK4a and Ki-67, benign and CIN 1 lesions showed a p16INK4a expression score of 0 or 1. But CIN 2 and CIN 3 lesions showed a p16INK4a expression score of 2 and 3, respectively.

Conclusions

The immunostain for p16INK4a and Ki-67 might be useful in reducing an inter-observer variability. But criteria for interpreting both markers should be strictly applied.

Abstract PDF

Ovarian primary malignant melanoma is very uncommon with only 44 reported cases in the literature. A 71-year-old woman with an ovarian mass and multiple nodules in the liver presented to our hospital. She was treated with bilateral salpingo-oophorectomy, and malignant melanoma was found in the mature cystic teratoma of the ovary. Malignant melanoma cells were also found in the ascitic fluid. She died 5 months later. Here we report a very uncommon case of malignant melanoma arising in an ovarian mature cystic teratoma with a review of the literature.

Abstract PDF: We report here on a rare case of a patient who presented with an extramedullary B lymphoblastic crisis as an initial manifestation of chronic myelogenous leukemia (CML). A 71-year-old man visited the emergency room due to suddenly developed dysarthria and right side weakness. Emergency craniotomy was done under the presumptive diagnosis of subdural hemorrhage. During the operation, a poorly demarcated firm mass was identified in the leptomeningeal space. Microscopically, the majority of the tumor was composed of monotonous immature cells with blast morphology, and these cells were immunoreactive for TdT, CD34, CD10 and CD20, indicating the precursor B-cell phenotype. The peripheral area of the tumor consisted of myeloid cells in various stages of maturation, and these cells were reactive for myeloperoxidase, chloroacetate esterase, CD43 and CD15. FISH analysis using the LSI bcr-abl dual color probe showed gene fusion signals in both the B-lymphoblasts and myeloid cells. The peripheral blood and bone marrow findings were consistent with CML with no evidence of a blast crisis. Cytogenetic study of the bone marrow demonstrated the 46, XY, t(9;22)(q34;q11) chromosome. A diagnosis of extramedullary B lymphoblastic blast crisis in a patient with Philadelphia chromosome-positive CML was made. Despite treatment, the patient died 3 months after he was diagnosed.

Abstract PDF

BACKGROUND
The epidermal growth factor receptor (EGFR) is known to be involved in many tumor promoting activities. EGFR inhibition has been tried as a therapeutic modality in many human malignancies.
METHODS
The expression of EGFR protein and the gene copy number changes were studied in 135 clear cell carcinomas and 16 papillary renal cell carcinomas (RCCs), and these tumors were diagnosed between 1995 and 1997.
RESULTS
An EGFR protein expression (2+ and 3+) was found in 54.1% of the clear cell RCCs and in 43.8% of the papillary RCCs. In the clear cell RCCs, its expression was associated with male gender, the tumor size (> or =4 cm) and high T stages (T2 and T3), with statistical significance. Trisomy and polysomy of the EGFR gene were found in 27 (25.7%) and 40 (38.1%) of 105 clear cell RCCs, respectively. Trisomy and polysomy were correlated with an EGFR protein expression and a high clinical T stage, with statistical significance. Among 15 papillary RCCs, 13 tumors showed trisomy (86.7%) and one showed polysomy (6.7%). Amplification was not found in both the clear cell and papillary type RCCs.
CONCLUSIONS
A considerable numbers of RCCs showed an overexpression of EGFR protein and increased EGFR gene copy numbers, yet the clinical significance of conducting a FISH study in RCC patients seems to be limited.

Abstract PDF

BACKGROUND
Langerhans cell histiocytosis (LCH) is a well-known neoplastic disorder of Langerhans cells which has characteristic findings, however, LCH has not been adequately studied in Korea.
METHODS
We analyzed the clinicopathologic features of 20 patients with LCH who were diagnosed between 1997 and 2006 at the Korea University Guro and Anam Hospitals.
RESULTS
The M:F ratio was 3:1 and the age ranged from 2-60 years (mean, 23.8 years [4 in 1st decade, 6 in 2nd decade, 2 in 3rd decade, 5 in 4th decade and 3> or =40 years of age). The cases were classified as unifocal unisystemic in 13 patients, multifocal unisystemic in 4 patients, and multifocal multisystemic in 3 patients. The bone was the most commonly involved organ (14), followed by lymph node (5), lung (2), skin (2) and ureter (1). The Langerhans cells were immunohistochemically stained with Langerin, CD1a, S-100 protein, and CD68. Langerin and CD1a were specific for Langerhans cells.
CONCLUSIONS
The distribution of the involved organs in patients with LCH was similar to the distribution in Western countries, but lymph node involvement was more frequent, whereas lung involvement was less common. Langerin is considered to be a specific marker for Langerhans cells.
