Idiopathic granulomatous orchitis.

Our paper reports 7 cases of idiopathic granulomatous orchitis. Testicular trauma and genitourinary tract infection were the only important conditions in the past history, and were possibly related to the etiology of this disease. The clinical appearance of idiopathic granulomatous orchitis varies, and it is difficult to differentiate from testicular cancer, the diagnosis usually being made on histological examination after orchiectomy. For young patients and those with single testis, inguinal exploration and frozen section are recommended.
