[Vasitis nodosa suspected of the spermatic cord tumor: a case report].

We report a rare case of vasitis nodosa. A 54-year-old man was found to have a right spermatic cord mass during the herniorrhaphy operation. There was no history of surgical or traumatic causes. An indurated mass in the right spermatic cord was suspected to be spermatic cord tumor, and a right high orchiectomy was performed. Histological examination revealed disruption of the ductal lumen, granulomas with the sperm-like necrotic tissue and proliferation of the lymphocytes and plasma cells in the smooth muscle bundles. Pathological diagnosis was vasitis nodosa.
