Abstract

Papillary serous peritoneal carcinoma(PSPC) is a rare malignancy that arises in the peritoneum and histologically resembles papillary serous carcinoma of the ovary. If peritoneal carcinomatosis occurs in the absence of an obvious primary tumor site and is associated with a papillary serous pathology, we may be dealing with the distinct entity of PSPC of extraovarian origin. Radiological findings suggesting the diagnosis are diffuse microcalcifications in the peritoneum, which occur in relation to psammoma bodies. The Ca-125 is most often abnormal and, not uncommonly, markedly elevated. The diagnosis requires that the surgeon identify grossly normal ovaries or minimal surface involvement. If PSPC is confirmed, a total abdominal hysterectomy, bilateral salpingo-oophorectomy, and aggressive debulking surgery should be carried out, followed by cisplatin-based chemotherapy. We report a case of PSPC arising from the rectum in a 41 year-old woman.
