title: Localized polyarteritis nodosa in the forearm and epididymis.
abstract: We report localized polyarteritis nodosa in a 31-year-old man who had painful nodules in the left forearm and scrotum. Histopathological findings of both tissues revealed distinct arteritis. However, he had no clinical evidence of any systemic disease. We finally diagnosed this case as a localized polyarteritis nodosa occurring in both the left forearm and epididymis. This form of polyarteritis nodosa has not been reported in the literature.
