Benign renal angiolipoma

Abstract A case of benign angiolipoma of the left kidney in a fifty-four year old woman is reported. The clinical, urographic and operative findings suggested primary renal cell carcinoma rather than a renal growth of mesenchymal origin. Neither cerebral symptoms characteristic of tuberous sclerosis complex nor the classical cutaneous findings were present in this case. The histopathologic studies of the specimen revealed a massive renal tumor made up of hemangiomatous and lipomatous benign elements. For this reason we believe that a pathologic diagnosis of benign angiolipoma of the kidney is justified and as such the case is reported.
