title: [Case of isolated polyarteritis nodosa appearing in bilateral epididymis].
abstract: A 50-year-old man visited our hospital with a complaint of painful masses in bilateral scrotums for 2 months. Ultra sonography shows isoechoic mass in both scrotum. Antibiotic was treated for 2 weeks but had no effects on scrotal swelling and testicular neoplasm cannot ruled out, so we performed bilateral high orchiectomy. Pathological examination shows necrotizing vasculaitis surrounded by glanulomas and pathologically diagnosed as Polyarteritis Nodosa in bilateral epididymis. After orchiectomy, blood examination of immunity was revealed no specific findings, that made us diagnosed as isolated PN. 2 years after operation, he had no reccurence.
