title: Coexistence of renal cell carcinoma and renal angiomyolipoma developing in a kidney: a case report.
abstract: Coexistence of renal cell carcinoma and angiomyolipoma in the same kidney is rare. A 54-year-old woman without tuberous sclerosis was admitted for further examination of incidental renal masses on ultrasonography. Computerized tomography revealed a 17-mm high density mass in the mediolateral portion of the right kidney and a 5-mm low density mass near the right lower pole. Because the former mass showed a typical tumor pattern on selective renal angiography and the latter mass was strongly hyperechoic on ultrasonography, a clinical diagnosis of renal cell carcinoma and angiomyolipoma was made. A right radical nephrectomy confirmed the preoperative diagnosis. She has been followed for 61 months with no recurrence.
