Based on histopathology and molecular genetics, ovarian carcinomas are divided into five main types: high-grade serous (70%), endometrioid (10%), clear cell (10%), mucinous (3%), and low-grade serous (<5%) carcinomas. These tumors, which ac…

Small cell carcinoma of the ovary, hypercalcaemic type (SCCOHT) is a lethal and sometimes familial ovarian tumour of young women and children. We and others recently discovered that over 90% of SCCOHTs harbour inactivating mutations in the …

This review article describes the main features of epithelial-to-mesenchymal transition (EMT) and its possible role in understanding myometrial invasion in endometrial carcinoma (EC), as well as the development of malignant mixed Müllerian …

It is currently thought that most clear cell and endometrioid carcinomas arise from ovarian endometriosis. We recently suggested that, besides their origin in the ovary, reduction of CDC42 messenger RNA (a member of the RHO GTPase family) m…

Primary squamous cell carcinoma of the ovary is extremely rare. We studied a 58-year-old woman in whom a keratinizing squamous cell carcinoma of the ovary had arisen from a mucinous cystic tumor of endocervical (müllerian) type. The tumor w…

Mullerian adenosarcomas are rare mixed tumors of low malignant potential that occur mainly in the uterus and also in extrauterine locations. Microscopically, they may be difficult to distinguish from adenofibromas. In this clinicopathologic…

Endometrioid carcinomas of the ovary closely resemble their uterine counterparts. It has been suggested that the former tumors have the same molecular alterations (microsatellite instability [MSI], PTEN, and beta-catenin) described in endom…
