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

Composite pheochromocytoma or paraganglioma of the adrenal gland is a well-recognized, yet extremely rare tumor with only one case reported in Korea. We report a case of incidentally found composite pheochromocytoma and ganglioneuroma of the adrenal gland in a 44-year-old female composed of intermingled components of pheochromocytom, ganglioneuroma, and cells with intermediate features. On immunohistochemical staining, the pheochromocytoma component was positive for synaptophysin and chromogranin, but negative for S-100 protein. Staining for the S-100 protein revealed sustentacular cells which formed a peripheral coat around the "Zellballen" and Schwann cells. The Fontana-Masson stain defined neuromelanin granules of ganglion cells and the ganglion cells expressed neural markers such as neurofilament proteins. Ultrastructural findings revealed pheochromocytes with a round or ovoid nucleus and occasionally prominent nucleolus containing numerous adrenaline and noradrenaline granules.

Abstract PDF

Traditionally, pathologists have used human biological material primarily for diagnostic purposes. More recently, advances in biomedical technology and changes in the research environment have placed new demands on pathologists and their handling of human materials. Moreover, these technological advances have required pathologists to be not only experts in diagnosis, but also managers of biobanks storing human biological material. Consequently, pathologists might now be confronted with unanticipated legal and ethical questions. We investigated seven examples of South Korean legislation concerning human biological material, including "The Bioethics and Safety Act" (2005), and we considered possible conflicts of interest between donors and researchers. We also reviewed international bioethical guidelines and legal precedents from several countries with special regard to pathologic glass slides, paraffin blocks, remaining specimens and other guidelines. We conclude that a better understanding of the legal and ethical questions concerning human biological material leads pathologists to safer and more conscientious management of these samples.

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.

Abstract PDF: Background
: This study was designed to investigate gastrointestinal neuroendocrine tumors with an emphasis on their clinicopathological characteristics.
Methods
: Sixty-five cases were reviewed and classified as typical carcinoid (TC), atypical carcinoid (AC), large cell neuroendocrine carcinoma (LCNEC) and small cell carcinoma (SmCC). We performed immunohistochemistry to characterize the expression of the immunoreactivity for synaptophysin, chromogranin, gastrin, somatostatin, thyroid transcription factor-1, p53 and Ki-67.
Results
: Most commonly, the tumors were located in the rectum (54%), followed by the stomach (23%) and colon (9%). Histologically, the tumors were classified as 49 TCs, 4 ACs, 6 LCNECs and 6 SmCCs. Most tumors were stained positive for synaptophysin and/or chromogranin. Four LCNECs and one SmCC were p53-positive. The carcinoids revealed a low level (<5%) of reactivity for Ki-67, while > or =30% of the cells showed reactivity for Ki-67 in the majority of LCNECs and SmCCs. Six patients with metastatic carcinoids were older than those patients without metastasis (64 vs 48 years, respectively, p=0.004). Furthermore, the size of tumors was larger for the patients with metastatic carcinoids than for the patients with nonmetastatic carcinoids (2.3 vs 0.5 cm, respectively, p=0.005).
Conclusion
: Old age, large tumor size and muscle invasion are associated with high grade neuroendocrine tumor and lymph node metastasis for those patients with carcinoids.

Abstract PDF: A micropapillary variant of urothelial carcinoma (MPC) is a distinct entity with an aggressive clinical course. It has a micropapillary configuration resembling that of ovarian papillary serous carcinoma. Its cytologic features have rarely been reported. We report a case of MPC detected by urine cytology. A woman aged 93 years presented with a chief complaint of macroscopic hematuria. Cytology of her voided urine showed clusters of malignant cells in a micropapillary configuration. Each tumor cell had a vacuolated cytoplasm, a high nuclear:cytoplasmic ratio, and irregular hyperchromatic nuclei. An ureteroscopic examination revealed exophytic sessile papillary masses extending from the left lateral wall to the anterolateral wall of the urinary bladder. A transurethral resection of the tumor was carried out. The tumor was characterized by delicate papillae with a thin, well-developed fibrovascular stromal core and numerous secondary micropapillae lined with small cuboidal cells containing uniform low- to intermediate-grade nuclei and occasional intracytoplasmic mucinous inclusions. These tumor cells infiltrated the muscle layers of the bladder, and lymphatic tumor emboli were frequently seen. Recognizing that the presence of MPC components in urinary cytology is important for distinguishing this lesion from low-grade papillary lesions and high-grade urothelial carcinomas can result in early detection and earlier treatment for an improved treatment outcome.

Abstract PDF: BACKGROUND
Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are the common malignant neoplasms of the skin. The p63 is a p53 homologue which is considered to be a reliable keratinocyte stem cell marker. Bcl-2 plays a key role in cell longevity by preventing apoptosis, whereas the bcl-6 gene functions as a transcriptional repressor. The p16-CDK4/6 complex arrests the cell cycle at G0 /G1 phase. In the present study, the expression of p63, bcl-2, bcl-6, and p16 in BCC and SCC was evaluated.
METHODS
Forty-seven BCCs and 43 SCCs were selected and microarrayed in paraffin blocks. Immunohistochemical analysis was performed with specific antibodies for bcl-2, bcl-6, p16 and p63.
RESULTS
p63 was found to be expressed in all BCCs and SCCs. Bcl-2 was exclusively expressed in BCCs (100%), but there was negative expression in SCCs, whereas bcl-6 was positively expressed in 18.2% of SCCs, and was negative in BCCs. In SCCs, p16 was expressed at high frequency (47.7%) than in BCCs (14.9%). The expression of p16 was correlated with the histologic grades of SCCs.
CONCLUSION
The different patterns of bcl-2, bcl-6, p63 and p16 protein expression between BCCs and SCCs may represent the different histogenesis and morphologic features of two lesions.

Abstract PDF: BACKGROUND
Angiogenesis is crucial for many biological processes such as embryogenesis, cyclic changes in the endometrium and wound healing. It is also critical for the growth, invasion and metastasis of solid tumors. Vascular endothelial growth factor (VEGF) acts as a mitogen for endothelial cells and is expressed by the presence of various tumor cells. The objective of this study is to evaluate if angiogenesis is involved in the mouse skin carcinogenesis and if VEGF is related to angiogenesis.
METHODS
We induced premalignant and malignant lesions on mouse (BALB/c) skin using the two stage chemical carcinogenesis moedl, DMBA (7,12-dimethylbenzanthracene) initiation and TPA (tetra decanoyl-phorbol-acetate) promotion. And we analysed the microvessel densities (MVD) and expression of VEGF in various stages of premalignant and malignant lesions by immunohistochemical studies.
RESULTS
Squamous papillomas, keratoacanthoma, dermatofibroma, and squamous cell carcinomas were developed in 20 weeks. There were no differences in the incidence of benign and malignant tumors between 10-week and 20-week promotion groups. There were significant increases in MVD from normal and hyperplastic skin through premalignant lesion to invasive squamous cell carcinoma (p<0.0005). But the degree of VEGF expression neither correlated with neither MVD nor the tumor groups.
CONCLUSIONS
Increased angiogenesis begins from the hyperplastic stage. VEGF produced by tumor cells may not play major roles in the angiogenesis in the two stage chemical carcinogenesis model of the mouse skin.

Abstract PDF: Aberrant crypt foci (ACF) are grossly unidentifiable lesions of the colon and visible only with low-power microscopic examinations after methylene blue stain. To establish the role of ACF in colorectal carcinogenesis, we evaluated the distribution, frequency, histopathological classification, and patterns of mucin secretion of ACF in the colon. A total of 142 aberrant crypt foci were found in 41 colectomy specimen for adenocarcinoma (36 cases) and benign diseases of colon (5 cases). Ten of 142 ACFs were in the ascending and transverse colon, 39 in the descending and sigmoid colon, and 93 in the rectum. The mean number of ACFs in the rectum (0.13 0.11/cm2) was higher than in the ascending and transverse colons (0.019 0.018/ cm2) and descending and sigmoid colon (0.10 0.14/cm2). ACFs were found only in cancer patients. One hundred and twenty ACFs among 142 ACFs identified by topology, were identified on histological examination. We classified ACFs into simple (48.3%), hyperplastic (42.5%), and dysplastic (9.2%) types. All ACFs were infiltrated by the lymphocytes in the stroma and 18 of these accompanied the lymphoid follicles. ACFs have variable histopathologic features and mucin profiles. Some variants of ACFs are at the early stage of the spectrum between benign and malignant.

Abstract PDF: Heat shock protein(HSP), first found in the MCF-7 human breast tumor cell line is one of the estrogen-regulated proteins and its synthesis is stimulated by estradiol. In this study, immunohistochemical staining was done for estrogen receptor(ER) and HSP on formalin-fixed, paraffin-embedded tissue sections in twelve normal cyclic and twenty carcinomatous endometria. 1) During the proliferative and early secretary phases, the nuclei of surface and glandular epithelial cells and stromal cells had moderate to strong staining for ER, whereas during the mid and late secretary phases, the glandular epithelial and stromal cells had weak staining for ER. The surface epithelial cells had positive staining of variable intensity. 2) From the early proliferative to mid secretary phases, the glandular and surface epithelial cells showed a positive reaction of variable intensity for HSP. In the late secretary phase, the glandular and surface epithelial cells showed a weak positive or a negative reaction for HSP. During the menstrual cycle, the stromal cells remained negative for HSP. 3) In adenocarcinomas of the endometrium, 8 of 11 (72.7%) well differentiated carcinomas were positive for both ER and HSP, while only 3 of 9(33.3%) moderately and poorly differentiated carcinomas were positive for ER and HSP. In conclusion, ER and estrogen-regulated heat shock protein(HSP) were closely related in normal and carcinomatous endometria and the reactivity was decreased according to poor differentiation.
