Extraovarian Primary Peritoneal Carcinoma: A Clinicopathological Gray Zone -

Extraovarian primary peritoneal carcinoma (EOPPC) is a rare disease entity, arising from extra ovarian peritoneum with abdominal carcinomatosis, uninvolved or minimally involved ovaries and no identifiable primary. Since an overlap of clinical manifestations and histologic appearances of EOPPC and papillary serous ovarian carcinoma exists, various diagnostic modalities like cytology, tumor markers, gross and histomorphological features, collectively help in arriving at a definitive diagnosis. As very few cases have been reported in literature, we hereby document one such interesting case.
