Epithelial ovarian cancer comprises a heterogeneous group of tumors. The four most common subtypes are serous, endometrioid, clear cell, and mucinous carcinoma. Less common are transitional cell tumors, including transitional cell carcinoma and malignant Brenner tumor. ⋯ High-grade serous carcinoma often has a transitional cell pattern, and adequate sampling in most cases shows more typical areas of serous carcinoma. Immunohistochemical markers are routinely employed in the diagnosis of epithelial ovarian carcinomas. However, molecular testing of these tumors, unlike in endometrial carcinoma, is not routinely used in clinical practice.
