Abstract

Liposarcoma, a malignant tumor originating from fat cells, is a rare occurrence in the retroperitoneal region. Surgical resection is the standard method for treating this cancer. This type of tumor is classified into common subtypes, which include well-differentiated liposarcoma and dedifferentiated liposarcoma. A 53-year-old male patient presented with lower left quadrant (LLQ) pain and melena for two weeks. Further diagnostic evaluation, including colonoscopy, revealed a 50 mm polyp in the hepatic flexure or distal of the ascending colon. The pathological assessment of the mass demonstrated a lipomatous lesion with a nuclear atypical lipomatous tumor, which was diagnosed as well-differentiated liposarcoma. The patient underwent surgical treatment and was discharged following his recovery. © 2025 Tehran University of Medical Sciences.
