Renal Angiomyolipoma Associated with Lymph Node Involvement and Renal Cell Carcinoma in Patients with Tuberous Sclerosis

Abstract

Renal angiomyolipomas are found in more than half of the patients with tuberous sclerosis. We report on 3 patients with tuberous sclerosis and pathologically aggressive renal angiomyolipoma with retroperitoneal lymph node involvement and/or renal cell carcinoma. All patients have had a benign course. The literature is reviewed and supports the benign nature of this seemingly aggressive disorder. An approach to the evaluation and treatment of a child with tuberous sclerosis and renal angiomyolipoma is presented.
