Testicular vasculitis: implications for systemic disease.
Nine cases of testicular vasculitis were identified from the surgical pathology and autopsy files of the Johns Hopkins Hospital. In three cases this was the initial manifestation of polyarteritis nodosa. Two of these men presented with recurrent testicular pain and fever, with orchiectomy samples showing focal infarcts and necrotizing vasculitis. The third man presented with epididymitis, with his biopsy specimen showing vasculitis. In two cases, men presented with systemic and testicular signs of polyarteritis nodosa, and the diagnosis was made on testicular biopsy and later studied at autopsy. In another case, the testicular lesions were seen with Goodpasture's syndrome; the patient was thoroughly studied at autopsy, and no evidence of polyarteritis nodosa was found. In the remaining three cases, testicular vasculitis was identified incidentally without diseases associated with vasculitis, one at orchiectomy for prostate adenocarcinoma and the other two at autopsy. Polyarteritis nodosa is the most common cause of necrotizing vasculitis of the testes, and pathologists should recognize the rare testicular presentation of this disease. However, testicular vasculitis also may be seen with other systemic diseases associated with vasculitis. Three of our cases were seen without systemic vasculitis, suggesting that testicular vasculitis may occur as an isolated finding without being a manifestation of systemic disease.
