Primary peritoneal serous adenocarcinoma mimicking carcinoma ovary with omental metastasis

Abstract

Primary peritoneal serous adenocarcinoma (PPSA) is a rare primary peritoneal tumor in women. Ovarian, tubal, and peritoneal serous carcinomas have similar pathologic findings. CA125 is the common biomarker used for diagnosis, monitoring treatment response, and tumor progression. To differentiate PPSA from metastasis of primary ovarian serous adenocarcinoma, histopathological criteria were laid down by gynecologic oncology group (GOG) for the diagnosis of PPSA. We present a case of primary peritoneal serous adenocarcinoma clinically mimicking ovarian serous adenocarcinoma with omental metastasis.
