Diagnosis Well- differentiated liposarcoma Discussion Retroperitoneal liposarcoma is among the most common primary retroperitoneal tumors, along with malignant fibrous histiocytoma and leiomyosarcoma. It is slow-growing and has a propensity to displace rather than invade adjacent structures. Liposarcoma is most often seen in the fifth to seventh decades and is more common in men. The appearance of fat in a retroperitoneal tumor can aid in diagnosis. Fat is invariably present in liposarcoma and notably absent in less well-differentiated masses.
Calcifications occasionally are visible.
