Abstract
The term cryptorchid refers to hidden testicle. Cryptorchidism can be either uni- or bilateral. Unilateral cryptorchidism usually occurs more commonly than the bilateral condition. Left testicular cryptorchid has an intraabdominal location, while right cryptorchid testis tends to be in the inguinal canal. The incidence of cryptorchidism seems to be higher in purebred and inbred dogs than in mixed-breed dogs. Primary testicular neoplasms are common in older dogs. Testicular interstitial cell tumors are more common in older dogs, and these tumors most often occur in cryptorchid testicles. This report describes the left intrainguinal canal cryptorchidism with histopathological finding of Leydig cell tumors in cryptorchid testicle and seminoma in unaffected testicle.
