Concurrent Oncocytoma and Two Angiomyolipomas in a Diabetic Kidney: A Very Rare Condition

Abstract

Angiomyolipoma (AML) and oncocytoma are uncommon benign neoplasms of the kidney which their simultaneous occurrence in the same kidney is extremely rare. This study reports a 60-year-old diabetic woman with the rare simultaneous occurrence of three renal masses. Histologic evaluation revealed two angiomyolipomas and one oncocytoma within the same kidney, in a background of histologic features of diabetic nephropathy. Renal angiomyolipoma and oncocytoma are uncommon neoplasms, and their simultaneous occurrence in the same kidney is extremely rare.
