Abstract

Liposarcoma is a malignant mesenchymal tumor that tends to develop in the retroperitoneal trunk and extremities. A 59-year-old woman came to our hospital with a chief complaint of abdominal pain. Computed tomography revealed an ovoid mass, 150mm in diameter, in the middle of the peritoneal cavity. Endoscopy showed an ulcerative tumor in the rectosigmoid. Anterior resection of the rectum and resection of the tumor were performed. Histological examination showed a well-differentiated liposarcoma that had developed in the ligamentum teres hepatis and an adenocarcinoma of the rectosigmoid. The present case of liposarcoma developing in the ligamentum teres hepatis is, to our knowledge, the first to be reported.<br>
