title: Asymptomatic renal cell carcinoma as a finding of Bardet Biedl syndrome.
abstract: Retinitis pigmentosa represents a class of disorders that exhibit dystrophy of the photoreceptors, pigment epithelium, and often systemic abnormalities, Bardet-Biedl syndrome is a form of retinitis pigmentosa that has characteristic non-ocular findings including polydactyly, obesity, learning difficulties, male hypogonadism, and renal anomalies. Though none of these renal anomalies are neoplastic, there is a 17 fold increased risk for renal cell carcinoma in obligate carriers of Bardet-Biedl syndrome. Herein, we describe a case of metastatic renal cell carcinoma discovered in a patient with Bardet-Biedl syndrome.
