Renal liposarcoma

Abstract

Introduction: Liposarcoma is a malignant mesenchymal tumor frequently located in retroperitoneum, and rarely presenting an isolated lesion in kidney. Case Report: Female, Caucasian, 49-year old patient, with family history of renal polycystic disease, was selected for organ donation. During preoperative examinations a renal pleomorphic liposarcoma was detected. She was treated with radical nephrectomy and remains asymptomatic, without evidences of recurrence in control ecographic examinations after a 4-year follow-up. Comments: Renal liposarcoma is a rare tumor. We report one case incidentally diagnosed during a routine pre-transplantation assessment in renal donor.
