ABSTRACT

Primary ovarian transitional cell carcinoma (TCC) is extremely rare tumor and recently it has been recognized as one of histologic subtype of ovarian epithelial carcinomas. Primary ovarian TCC has been classified as a different subtype from malignant Brenner tumor for it's histologic and clinical characteristics. Several recent studies repoert immunohistochemical stains are helpful to differentiate this tumor from TCC of bladder. Primary ovarian TCC usually presents at an advanced stage and behaves aggressively however, these tumors appear to be more sensitive to chemotherapy than other ovarian carcinomas and may have a better prognosis. We experienced two cases where operation and chemotherapy have made for primary ovarian TCC patients and report our own case studies with a brief literature review.
