Half of the patients with renal cysts develop clear cell carcinoma. VHL is a rare autosomal dominant disease characterized by abnormal angiogenesis with benign and malignant tumors affecting multiple tissues. It is inherited as a mutation in one allele of the VHL tumor-suppressor gene. Ref: Harrisons Internal Medicine, 18th Edition, Chapters 284, 379
