title: [A case of retroperitoneal liposarcoma].
abstract: A 77 year-old woman presented with the chief complaint of a mass in the right upper quadrant. The examination on admission including IVP, echography, Ga scintigraphy, barium enema, CT scan, and angiography revealed that the right kidney and ascending colon were displaced by the mass. Under the diagnosis of retroperitoneal tumor, operation was carried out. Most of the mass was resected with the right kidney. The pathological diagnosis of the resected tumor revealed well differentiated liposarcoma. Convalescence was uneventful and the patient has been well and free from disease for 14 months. Based on our experience and the review of the pertinent literature in English and Japanese, we emphasize the importance of definite surgery and close follow up, as liposarcoma is frequently recurrent.
