Abstract |
We report a case of tuberous sclerosis ( TSC) associated with renal cell carcinoma and angiomyolipoma in a patient, who developed endstage renal failure that required hemodialysis after nephrectomy. A 37-year-old woman with TSC was admitted for further investigation of bilateral renal masses detected by computed tomography (CT). Angiography revealed a tumor stain (4 cm in diameter) in the medial portion of the right kidney. Because renal cell carcinoma (RCC) was strongly suspected, right nephrectomy was performed. Her serum creatinine level was already increased, moderately, at 2.4 mg/dl, before the right nephrectomy. Her renal function deteriorated quickly (in 1(1/2) years) after the right nephrectomy, and hemodialysis was introduced the next year. The histological findings of the resected right kidney revealed marked intimal thickening of the intralobular arteries. These findings suggested that the renal function loss was not only caused by the nephron mass reduction due to the nephrectomy but was also caused by nephrosclerosis. Though most patients with TSC die before developing endstage renal failure, this patient is currently receiving maintenance hemodialysis and has been followed for 3 years with no recurrence of RCC in the left kidney.
