An unusual scrotal lump.

Polyorchidism is a rare anomaly of the genital tract in which supernumerary testes are present, usually within the scrotum. Less than 100 cases have been reported in the literature. We present a case of polyorchidism in which the diagnosis was made on ultrasonography and as there was no evidence of an associated pathology on clinical examination or imaging, surgical exploration was therefore not considered necessary.
