Background: Congenital uterine malformations are rarely identified in domestic and human animals and are related to problems during the embryonic formation of the paramesonephric ducts. Cases of agenesis and segmental aplasia or unicorn uterus have been described in bitches, but there are no reports of total uterine aplasia in this specie. The report of a case of total uterine aplasia and segmental atrophy of the cranial vagina, accidentally diagnosed is reported herein.Case: An adult female bitch without defined breed in bad general condition was attended in the emergency service in a Veterinary Hospital. During anamnesis the information was restricted because it was an errant animal rescued for the consultation, but accompanied for at least 12 months in the environment in which it lived. Data related to the estrous cycle were unknown, but no gestation was observed in the last year. Investigations detected anemia and intense thrombocytopenia, azotemia and increased alanine aminotransferase. Two days later, with no progression, images suggestive of hemometra/ mucometra were observed during abdominal ultrasonography, and the patient underwent emergency ovariohysterectomy despite the general poor condition. Before the procedure the uterus was not routinely identified, but a fibromuscular, nontubular and thin structure occupied the region corresponding to the horns and uterine body, thickening in the cervix region. Death four days after surgery and sent to necropsy. During necropsy it was observed that the vulva and the vestibule of the vagina did not present macroscopic alterations, however there was a marked digitiform narrowing of the cranial region of the vagina, which ended in blind bottom. The mucosa in this narrowing was smooth, without folds. The microscopic structure of the ovaries, uterine tubes and caudal vagina were preserved.[...](AU)
