Aggressive diagnostic approach indicated in testicular sarcoidosis

A twenty-nine-year-old black male presented with a testicular mass and hilar adenopathy. Histologic sections of the testis showed the 3 by 2 by 2-cm mass was an inflammatory granuloma due to sarcoidosis. The epididymides were involved bilaterally. The initial differential diagnosis included: sarcoidosis, testicular neoplasm, an infectious process, or a combination of the three. Biopsy of the testicle is recommended to confirm the diagnosis of sarcoidosis. We believe there are only 6 reported cases of clinically detected testicular sarcoidosis.
