Plain-English summary
A 7-year-old male miniature schnauzer was brought in for surgery to remove an undescended testis (unilateral cryptorchidism). During the procedure, the vet discovered a fully formed uterus attached to the testis, a condition known as persistent Müllerian duct syndrome. This rare condition was accompanied by cystic endometrial hyperplasia and a solitary tumor in the undescended testis. The dog underwent surgery successfully, and while persistent Müllerian duct syndrome is uncommon, it is seen more often in miniature schnauzers due to genetic factors.

Abstract
A 7-year-old male miniature schnauzer dog with unilateral cryptorchidism was presented for elective orchiectomy. Surgery to remove the cryptorchid testis revealed a fully formed uterus with horns attached to both testis and the body and cervix terminating at the prostate gland. The gross and microscopic diagnosis for the genital tract was persistent Müllerian duct syndrome with unilateral cryptorchidism. Additional associated lesions included cystic endometrial hyperplasia and a solitary, intratubular seminoma within the undescended testis. Persistent Müllerian duct syndrome is rare among domestic animals but is more common in miniature schnauzer dogs because of inheritance as an autosomal recessive trait.
