Volume 11, Number 2Case ReviewGenitourinary SarcoidosisEdmund S SabaneghPravin K RaoGenitourinary involvement of sarcoidosis can mimic many common urologic conditions. Although sarcoidosis is a benign inflammatory condition, it can present much like malignant or infectious conditions; thus, failed diagnosis can lead to unnecessary medications or surgical procedures. In addition, management choices for patients with scrotal findings have important implications for future fertility. Thus, this uncommon condition should be on the differential diagnosis for any urologic patient. The authors report on a patient with a scrotal mass as his presenting symptom of sarcoidosis and review the diagnosis, implications, and management of sarcoidosis involving all potential sites in the urinary tract.[Rev Urol. 2009;11(2):108-113]UrologySarcoidosisGenitourinaryScrotal mass
