Symptomatic kidney involvement in a child with tuberous sclerosis.

ABSTRACT

Tuberous sclerosis complex is an autosomal dominant disorder of cellular proliferation and differentiation with variable penetrance and a high spontaneous mutation rate that affects multiple organs, including the kidney. Kidney involvement is commonly asymptomatic and bilateral, and rare in childhood, especially under 10 years. Herein, we report a case of unilateral renal angiomyolipoma in a nine-year-old girl with tuberous sclerosis who had symptoms of pain and macroscopic hematuria.
