[Sarcoidosis with epididymal and testicular lesions: case report and a review of the literature]

A 47-year-old man was admitted for further examination of uveitis. He had noticed scrotal swelling before his admission. A computed tomographic scan of the chest showed hilar and mediastinal lymphadenopathy, multiple micronodules and thickening of the interlobular septum, and these findings were consistent with sarcoidosis. Bronchoalveolar lavage fluid showed lymphocytosis. Gallium-67 scintigraphy revealed an abnormal accumulation in the hilar and mediastinal lymph nodes and in the bilateral scrotum. The resected and biopsied specimens of the epididymis and testis demonstrated numerous noncaseating epithelioid cell granulomas but no evidence of neoplasm. Therefore, systemic sarcoidosis was diagnosed. A review of the Japanese literature found most cases to be associated with a history of painless scrotal swelling with chest roentgenogram findings of stage I or II, while also indicating it was important to perform biopsy or surgically resect any epididymal and testicular lesion.
