Polyorchidism; unilateral, one atrophic undescended double testicles.

Polyorchidism is a very rare genitourinary anomaly defined with the presence of more than two testicles. Polyorchidism is associated up to 40% with undescended testicles. The present report is about an incidentally detected triorchidism case with unilateral, one atrophic undescended double testicles. A 4-year-old child, diagnosed with undescended left testicle revealed during orchiopexy polyorchidism with distinct epididymis and vas deferens. Whereas one of the testicles was in regular size; the other two were atrophic. Orchiectomy was conducted on the atrophic testicle and orchiopexy to the regular size testicle. The atrophic testicle excised was referred histopathological analysis and was diagnosed as atrophic testis. The patient discharged on the first postoperative day, was considered as normal during postoperative evaluation made on the third postoperative day. Polyorchidism is a rare genitourinary abnormality, and its management is still controversial. Yet, we believe that orchiectomy is to be conducted in atrophic testicle cases.
