Isolated polyarteritis nodosa of the male reproductive system associated with a germ cell tumor of the testis: a case report.
Polyarteritis nodosa (PAN) presents mostly as a systemic disease with poor prognosis, rarely in an isolated form with a usually favorable outcome. Both forms may affect the male reproductive system and both forms have been associated with malignancies. We describe for the first time the occurrence of isolated PAN in the reproductive system combined with a mixed germ cell tumor of the testis in a 21-year-old man presenting with symptoms of chronic epididymitis. Two years after surgery he is without evidence of recurrence of either the tumor or PAN.
