Abstract

Psammocarcinoma is a rare type of serous carcinoma arising from the ovaries or the peritoneum. Histopathologically, it has large deposits of psammoma bodies, invasion to surrounding tissues, and low-grade cytologic atypia. Biologic behavior is similar to borderline serous tumors with a favorable survival time. Primary surgical debulking with complete resection of the tumor should be the main surgical approach, while the benefit of postoperative chemotherapy remains unknown. A new case of primary peritoneal psammocarcinoma with survival after an initial diagnosis of 5.5 years is presented with a literature review.
