A Rare Case of Sarcoidosis With Urologic Symptoms As the Presenting Feature.

Sarcoidosis is a multisystem idiopathic disease that can affect virtually any organ of the human body. However, genitourinary tract involvement is rare. We describe the case of a 33-year-old man with post-coital right scrotal pain. Scrotal ultrasound showed two vascularized nodular lesions in the right testicle and one in the left. A thoracic and abdominopelvic computed tomography scan showed micronodular infiltrate in the liver, spleen, lungs, and millimetric retroperitoneal and iliac lymph nodes. Levels of alpha-fetoprotein and human chorionic gonadotropin beta were normal. On positron emission tomography, the previously documented micronodular infiltrate exhibited features suggestive of an inflammatory etiology. The aspiration cytology of an iliac ganglion was described as normal, with no malignant cells. A liver biopsy revealed non-caseating epithelioid granulomas characteristic of granulomatous hepatitis. After exclusion of other causes of granulomatous inflammation, conjugation of clinical and histological features led us to the diagnosis of sarcoidosis with pulmonary, hepatic, splenic, and genitourinary involvement. This clinical report describes one of the rare occasions when the reproductive tract is affected by sarcoidosis and is the first organ to present signs of involvement by the disease, which reinforces the importance of considering sarcoidosis in the differential diagnosis of urologic conditions. The diagnosis of testicular sarcoidosis is challenging and the issue of its impact on fertility is particularly important.
