The kidney in tuberous sclerosis.

Tuberous sclerosis is essentially a hereditary disease dominated by hamartomas in various organs. Symptoms of the disease are referable to expanding growth of these hamartomas, especially in the kidney where these benign lesions most often present with pyuria, hematuria or pain from bleeding. They are apt to be erroneously diagnosed as malignant both clinically and microscopically. Renal symptomatology is most often to be found in the adult patient.
