後腹膜脂肪肉腫の1例

Abstract

A 65-year-old woman with the chief complaints of a mass in the left upper quadrant and fever is presented. The examination on admission including IVP, barium enema and splenic scintiphotography revealed that the left kidney, the descending colon and the spleen were displaced by the mass. Under the diagnosis of retroperitoneal tumor, operation was performed. The left kidney, the spleen, a part of the descending colon and the tail of the pancreas were also resected en bloc because the tumor had invaded these organs. The pathological diagnosis of the resected tumor was well-differentiated liposarcoma that was partly pleomorphic. The postoperative Course was uneventful and the patient has been well and free of disease for 3 years. Based on our experience and a review of the pertinent literature in English and Japanese, we emphasize the importance of definite surgery and close followup, as liposarcoma is frequently recurrent.
