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
- Cytokeratin 7 has been known to be present in various types of human epithelial cells including the ovarian neoplasms, but not in colon cancers. The antibody to colon ovarian tumor antigen (COTA) has been introduced as a marker of colon and ovarian tumors. The aim of this study was to evaluate the usefulness of cytokeratin 7 and COTA in the differential diagnosis between ovarian primary and metastatic tumors. Nineteen primary ovarian epithelial tumors, seven metastatic carcinomas of the ovary from the stomach, three metastatic carcinomas of the ovary from the colon, one mucinous tumor of the ovary associated with a mucinous tumor of the appendix and pseudomyxoma peritonei, and nineteen colonic and twenty gastric adenocarcinomas were stained with monoclonal antibodies to cytokeratin 7 and COTA. The results are summerized as follows; In the primary ovarian tumors, 94.4% were positive for cytokeratin 7 and 50% were positive for COTA. In the primary colonic adenocarcinomas, 94.7% were negative for cytokeratin 7 and 68% were positive for COTA. In the metastatic ovarian tumor from the colonic adenocarcinomas, 100% were negative for cytokeratin 7 and positive for COTA. In the primary gastric adenocarcinomas, 40% were negative for cytokeratin 7 and 85% were negative for COTA. In the metastatic ovarian tumor from the gastric adenocarcinomas, 43% were negative for cytokeratin 7 and 14% were negative for COTA. From the results of this study, it could be concluded that in the differential diagnosis of primary ovarian tumors from metastatic colonic carcinomas, positive reaction for cytokeratin 7 suggests a primary ovarian tumor but a negative reaction for cytokeratin 7 and positive reaction for COTA suggest metastatic colonic carcinomas. The results of this study also reveal that cytokeratin 7 and COTA are not useful in the differential diagnosis of primary ovarian tumors from metastatic gastric carcinomas.

Abstract
PDF
- An ovarian sex cord tumor with annular tubules(SCTAT) in an 18-year-old woman who had secondary amenorrhea but not Peutz-Jeghers syndrome was studied by light and electron microscopy. Her clinical features were consistent with those of Turner's syndrome, i.e, shortness of stature, webbing of the neck, scanty or absent axillary and pubic hairs, lower hair line with streak gonad. Chromosomal analysis revealed 45, X/46, XX karyotype. The patient has been well and disease free for a period of 2 years after surgical removal of tumor. Histologically, the tumor was composed of nests of cells arranged in simple and complex annular tubules with central acidophilic hyaline bodies. Ultrastructurally, the cells had deeply indented nuclei and the cells were joined by specialized intercellular junctions along their lateral adjacent borders. Central acidophilic hyaline body consisted of concentric lamellae of basal lamina, but Charcot-Boettcher filaments were not observed.

Abstract
PDF
- Forty-four ovairan tumors were immunohistochemically studied for the presence of broad-spectrum keratin, vimentin, desin, carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), and alpha 1-antitrypsin (AAT) in formalin-fixed, paraffin-embedded tissues. 1) Among the common epithelial tumors, all the serous carcinomas (4) expressed keratin and AAT, and one additionally CEA. Six mucinous carcinomas exhibited keratin-positivity in two. One endometrioid carcinoma coexpressed keratin and vimentin as well as AAT, but one clear cell carcinoma expressed only keratin. Keratin-and CEA-positivity in epithelial cell nests and vimentin-positivity in stromal cells were observed in two Brenner tumors. Two undifferentiated carcinomas showed keratin-positivity in one and focal CEA positivity in the other. 2) In sex cord-stromal tumors, four out of six granulsa cell tumors, all four thecomas and three fibromas expressed vimentin, and two granulosa cell tumors and two thecomas showed AAT-positivity. The others were negative. 3) Among germ cell tumors, four dysgerminomas showed focal vimentin-positive cells in two and diffuse staining for AAT. Seven endodermal sinus tumors expressed AAT in all. Additionally, AFP were positive in two and CEA in three out of them. One embryonal carcinoma expressed CEA, AAT and AFP. 4) In four metastatic carcinomas, three exhibited keratin-and CEA-positivity, whereas one exhibited keartin-and vimentin-positivity. All showed AAT-positivity. 5) There was no positive case for desmin among ovarian tumors.

Abstract
PDF
- A case of Juvenile Granulosa Cell Tumor (JGCT) of the ovary with unusual pleomorphic histologic and malignant biologic behaviour is described. The tumor occurred in a 10-year-old girl and was associated with clinical features of isosexual pseudoprecosity and a marked elevation of serum estradiol. The mass manifested initially in the right ovary and subsequently involved the contralateral ovary. A multi-organ metastasis developed during a 6-month-interval despite chemotherapy. She received two operations at 6-month interval, and tissues were obtained from the tumor mass. A marked histologic difference was observed between these two samples. The second biopsy showed profound cellular pleomorphism with numerous multinucleated tumor giant cell formation and hyaline bodies. The differential diagnosis from germ cell tumor and the possible factors for the pleomorphism are discussed.
