Swelling of the testis or the surrounding tissues in the scrotum. Harmless and painless swellings include epididymal cysts, hydroceles, varicoceles, and spermatoceles. Cancer of the testis (see testis, cancer of) is rare but may be a cause of painless swelling. Swelling that is painful may be caused by a direct blow, torsion of the testis (see testis, torsion of), orchitis, epididymo-orchitis, or, in very rare cases, cancer of the testis. Any swelling of the testes should be assessed promptly by a doctor.
