Epithelial tumors of the ovary: A review focusing on carcinoma and recent advances

Ovarian carcinoma includes a wide variety of entities and appropriate subclassification is one of the chief goals in diagnostic gynecologic pathology. Over the years, several new entities have been added to the list of ovarian carcinomas. Moreover, recent advances in the pathogenesis of newer and “older” types of ovarian carcinoma have allowed for the development of ancillary studies that are important in both the subclassification and prognostication. The surgical pathologist must assimilate these new discoveries in ovarian carcinoma in addition to refining their morphology-based diagnostic skillset. The purpose of this review article is to provide an overview of specific genetic factors, clinical disease states, and microscopic queues that are important in the subclassification of ovarian carcinoma.
