Discussion

Liposarcoma is the most common soft tissue sarcoma with a peak incidence in the 5th decade. It usually involves the thigh, lower leg, retroperitoneum, or buttock. Metastases are uncommon with well differentiated tumors but occur more frequently with pleomorphic and round cell types. Lungs and viscera are the most common sites for metastases.
