Pseudo-hermafroditismo masculino em cão com síndrome da persistência dos ductos de Müller: relato de caso

Abstract

Male pseudohermaphroditism is a disorder of sexual development characterized by a discrepancy between genetic sex and phenotypic differentiation. This report describes the case of a 7-month-old mixed-breed dog treated at the Veterinary Hospital of UFPB, presenting with a vulvar mass. Clinical examination revealed ambiguous genitalia and a nodule lateral to the vulva. Imaging studies indicated the presence of an osseous structure in the vulvar region and ectopic testes. The diagnosis was confirmed through cytological and histopathological examinations, which revealed dysfunctional testes with severe tubular degeneration. Surgical treatment included orchiectomy, penectomy, and hysterectomy. This case highlights the importance of early diagnosis and appropriate surgical management of disorders of sexual development in dogs.
