Expression of CD44S in benign, borderline, and malignant serous epithelial ovarian tumors / 대한산부인과학회잡지

OBJECTIVE: To determine the CD44S expression in the development and progression of serous ovarian tumor. METHODS: An immunohistochemical stain was undertaken of a series of 12 cases of benign, 15 cases of borderline, 30 cases of malignant serous ovarian tumors. Then, we analyzed the expression of CD44S to see whether expression of this adhesion molecule by tumor cells correlated with clinicopathological factors. RESULTS: In twelve benign tumors, CD44S was not expressed. Four of fifteen (27%) borderline tumors were positive for CD44S. Twelve of thirty (40%) malignant tumors were positive for CD44S. CD44S expression rate was significantly associated with non-benign tumors (P=0.003). But, there was no significant correlation between CD44S expression and stage, grade, peritoneal seeding or lymph node metastasis. CONCLUSION: Since benign ovarian tumors show negative CD44S, positive CD44S can provide partial diagnostic aid in ovarian malignant tumor.

A case of Krukenberg tumor of ovary metastases from ductal type breast carcinoma / 대한산부인과학회잡지

Krukenberg tumor of the primary breast carcinoma is rare and this is almost invasive lobular carcinoma. They are usually bilateral and frequent in premenopausal women. Diagnosis of symptomatic Krukenberg tumor is reported to be 1 or 2 year after the diagnosis of primary neoplasm. But sometimes it is discovered prior to the detection of the primary breast carcinoma. Unexpected ovarian micrometastasis was recognized after oophorectomy of normally appearing ovaries in breast cancer patients. Existence of Krukenberg tumor means advanced primary disease and possible metastasis to other organs, and have a poorer prognosis. We report a case of Krukenberg tumors occurred 3 years after the diagnosis of primary ductal type breast carcinoma.
