Abstract

Liposarcoma is the most common soft tissue malignant tumor. It mostly arises in the subcutaneous tissue of shoulders, limbs, neck, and retroperitoneal space, but abdominal wall occurrence is very rare. Atypical lipomatous tumor (ALT) is a well-differentiated liposarcoma (WDLPS) and constitutes 40-45% of all liposarcoma cases. A 47-year-old male was admitted due to subcutaneous tumor. MR examination showed a mass with heterogeneous contrast in the lower abdominal wall. The patient was operated under spinal anesthesia. Adipose tissue of the lower abdominal tissue was removed. Postoperative course was uneventful. The final histopathological diagnosis was atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDLPS). The patient remains under surgical care.
