Two cases of male pseudohermaphroditism in the dog. Clinical, macroscopic, karyotypic and therapeutic features.

Abstract

Two cases of male pseudohermaphroditism in the dog are described, including clinical, macroscopic, microscopic, karyotypic and therapeutic features. The external appearance of both dogs was that of an otherwise normal bilateral cryptorchid. Both dogs developed signs of male feminizing syndrome at 7 and 5 years of age respectively. This prompted exploratory laparotomy, disclosing an uterus, testes at the ovarian sites and Sertoli cell tumours. It is emphasized to include malformations of the genital apparatus in the differential diagnosis of canine urological and endocrine disease.
