Cecal Liposarcoma with Ascending Colon Carcinoma—A Case Report—

Abstract

An 83-year-old woman with anemia was diagnosed with multiple ascending colon tumors on colonoscopy and was referred to our hospital for surgery, considering the risk of tumor-induced bleeding or obstruction. Contrast-enhanced abdominal computed tomography revealed a tumorous lesion and invagination in the ascending colon. We performed open surgery, and intraoperatively we detected ascending colon carcinoma (pT3N1aM0, Ly1a, V0, pStage III b) and cecal liposarcoma, which showed anterograde invagination.

A liposarcoma most commonly occurs in the extremities and retroperitoneum, and a colonic liposarcoma is rare. We report a case of cecal liposarcoma and concomitant ascending colon carcinoma that occurred as multiple primaries, along with a literature review.
