[Renal cell carcinoma associated with tuberous sclerosis: a case report].
Renal angiomyolipoma associated with tuberous sclerosis is well known. On the other hand, few cases of renal cell carcinoma in connection with tuberous sclerosis have been reported. We report a patient with tuberous sclerosis whose kidney was involved with renal cell carcinoma. A 18-year-old woman was first admitted in August 1987 for evaluation of left renal tumor. Diagnosis of tuberous sclerosis was made when she was 11 years old on the basis of mental retardation, papules on her face, seizures, white leaf-shaped macules and periventricular calcifications. Computerized tomographic scan demonstrated a large mass arising from the left kidney and small masses in the right kidney. Angiography confirmed bilateral hypervascular renal tumors. On these bases, a clinical diagnosis of bilateral renal angiomyolipomas was made and surgical treatment of the left kidney was recommended because of its large size. However, her parents did not permit treatment until March, 1988. Finally, left nephrectomy of 4,750 g was performed and histological examination revealed renal cell carcinoma with clusters of spindle cells. In the literature available to us, we found twelve reports of malignant renal tumors associated with tuberous sclerosis including five renal cell carcinomas in Japan.
