title: Spontaneous retroperitoneal hemorrhage: unusual presentation of renal cancer.
abstract: Spontaneous retroperitoneal hemorrhage as the presenting sign of renal cancer is rare. A case of spontaneous retroperitoneal hemorrhage from a renal carcinoma is described and management possibilities presented. While it is true that renal angiomyolipomas are the main cause of spontaneous retroperitoneal renal bleeding, the possibility of renal cancer should be entertained more often in the differential diagnosis.
