Ninety per cent of ovarian cancers are derived from the ovarian surface epithelium and these neoplasms are classified into serous, mucinous, endometrioid, clear-cell and transitional-cell types. The molecular pathology of ovarian carcinomas is heterogeneous and involves various putative precursor lesions and multiple pathways of development. The most common subtype, high-grade serous carcinoma, is characterized by p53 mutations, and BRCA1 and/or BRCA2 dysfunction. It most likely arises from epithelium within inclusion cysts or from the surface of the ovary. In contrast, low-grade ..View full abstract
