The vlue of epinephrine enhanced angiography in the preoperative distinction of isolated hamartoma (angiomyolipoma without stigma of tuberous sclerosis) from hypernephroma has been largely discounted in the past. The authors performed this procedure in 6 patients (4 with isolated hamartoma and 2 with tuberous sclerosis complex). Vasoconstriction of the tumor vessels in the isolated group suggested the benign nature of the hypervascular mass in all cases. Vasoconstriction stronger than that of normal parenchymal vessels suggested the diagnosis of isolated renal angiomyolipoma. This form of pharmacoangiography should be part of the routine preoperative workup of all solid renal masses.

Renal cell carcinoma (RCC) is the most common tumor of the kidney. Angiomyolipoma is frequently present in the patient who has the stigma of tuberous sclerosis. We reported a case of a 39-year-old female, without the stigma of tuberous sclerosis, who was admitted on account of a firm, huge, fixed and palpable mass over the left flank region for one week. After radical nephrectomy, the pathological report was renal cell carcinoma, granular cell type, associated with angiomyolipoma. The literature concerning this unusual case is reviewed.
