[Perineal ectopic testis].

Three further cases of perineal ectopic testis are reported and the published literature reviewed. Etiopathogenicity is discussed and emphasis placed on the need for perineal exploration in all cases of absence of testes from the scrotum. The most effective route of approach for repair is an inguinal one allowing replacement of the testis into the corresponding hemiscrotum without difficulty. Because of the histopathologic features involved, prognosis is better than that of cryptorchidism.
