Abstract
This reports a 71-year-old man whose chief complaiant was a feeling of fullness in the abdomen. CT scan showed the right kidney was displaced from the right dorsal side, and a huge tumor occupied the right peritoneal cavity. Fat concentration was significantly higher among the various densities observed in the interior of the tumor and the right kidney was buried in the tumor. Retroperitoneal liposarcoma was diagnosed, and retroperitoneal tumorectomy and partial resection of the right adrenal gland together with the right kidney were carried out. The resected specimens weighed 7.9 kg. Histopathological diagnosis was myxoid liposarcoma. As the effect of radiation therapy and chemotherapy on liposarcoma has received little evaluation, a follow-up is under way without adjuvant treatments.
