Abstract: The most common histological type of retroperitoneal sarcomas is liposarcoma. Renal papillary cancers account for approximately 10% of all known renal cell cancers and nephrectomy is the preferred choice for the treatment in suitable cases. In this report, we presented a concurrency of giant retroperitoneal liposarcoma and renal papillary cancer in a 61-year-old male patient. He was referred to our clinic with complaints of abdominal distension and pain. Computed tomography (CT) scan, magnetic resonance imaging (MRI) and positron emission tomography-computed tomography (PET-CT) revealed a giant mass filling intraabdominal and retroperitoneal space, approximately 50x30 cm in size and also a separate mass which is 6x8 cm in size in the upper pole of the left kidney. The giant mass was excised in two separate pieces. After frozen section procedure, nephrectomy was performed for mass arising from the left kidney. Histopathological analysis of the large masses, revealed dedifferentiated liposarcoma and renal papillary cellular cancer in the abdomen and left kidney, respectively. In conclusion, a second primary tumor can be seen in patients with giant retroperitoneal liposarcoma and coincidence of these tumors must be determined in the preoperative period for appropriate treatment.
