case_images: She underwent CT scan of the abdomen (Figures 1-3) and pelvis that demonstrated enlarged left periaortic lymph nodes, mild left hydronephrosis, narrowing of the sigmoid colon, and a large multi-cystic mass in the midline pelvis measuring 12.5 x 9.9 x 11.7 cm.

case_images: Due to the concern for sigmoid stenosis and history of intermittent bloody bowel movements she also underwent colonoscopy (Figures 4, 5) that showed stenosis due to external compression with mild mucosal ischemic changes without intraluminal lesion.

case_images: Gross pathology (Figures 6, 7) revealed primary peritoneal carcinosarcoma measuring 7.5 x 6 x 4.5 cm.
case_images: Squamous portion of the tumor. Demonstrates keratinization and intracellular bridges. There is a variation in size of the nuclei, there is nuclear atypia and prominent nucleoli.
