Abstract

Liposarcoma is the most common soft tissue sarcoma in adults and accounts for 9.8% to 16% in all soft tissue sarcomas. The common sites include limbs, buttocks, and retroperitoneum, et al. The early diagnosis of retroperitoneal liposarcoma may be difficult because of due to the late onset of symptoms and the tumors are frequently noted in a large size with the involvement of adjacent structures. Surgical therapy remains the most effective modality for the treatment of retroperitoneal liposarcoma. But, complete surgical resection of these tumors is often challenging and, at times, may be impossible. So, adjuvant radiation therapy is necessary for the improvement of prognosis in many cases. We report a case of retroperitoneal liposarcoma which was treated with complete surgical resection followed by adjuvant radiation therapy.

Key Words: Liposarcoma, Retroperitoneum, Complete surgical resection, Adjuvant radiation therapy
