A rare case of extraovarian primary peritoneal carcinoma in a 72 year-old woman.

Background Extraovarian Primary Peritoneal Carcinoma (EOPPC) was first described by Swerdlow in 1959 [1]. Basically, EOPPC is a malignancy that spreads widely inside the peritoneal cavity involving mostly the omentum with minimal or no ovarian involvement. Most of the EOPPC cases reported have been of serous histology; histopathological, immunohistochemical, and clinical similarities have been observed between EOPPC and Epithelial Ovarian Cancer (EOC).
