Primary peritoneal serous carcinoma (PPSC) is a rare entity that diffusely involves the pelvic peritoneum seen predominantly in elderly postmenopausal women. The worldwide incidence is unknown because of the lack of large multicentre studies. PPSC are difficult to diagnose preoperatively as radiological investigations fail to interpret peritoneal infiltration. The histopathological criteria laid down by Gynaecology Oncology Group GOG helps to distinguish between primary peritoneal carcinoma and peritoneal metastasis from primary ovarian carcinoma.
