[Epididymal sarcoidosis: a case report].

A rare case of epididymal sarcoidosis is reported. A 52-year-old man was admitted with a painless mass in the left scrotum. An operation revealed that a 1-cm mass was located at the epididymal head and well demarcated from the testis and the surrounding tissue. Epididymectomy was performed. Histopathological diagnosis was noncaseating granulomas consistent with sarcoidosis. Systemic examination showed bilateral hilar lymphadenopathy and bilateral peripheral anterior synechiae, but these lesions were diagnosed as inactive. Serum level of angiotensin-converting enzyme was normal.
