Aplasia uterina total em cadela

Abstract

Congenital uterine malformations are rarely identified in domestic animals, and are related to errors during the embryonic formation of the paramesonephric ducts. The report of an unpublished case of total uterine aplasia and segmental atrophy of the cranial vagina, accidentally diagnosed at the Federal University of Mato Grosso, is the objective of this study. A fibromuscular, non-tubular, thin structure occupied the region corresponding to the horns and uterine body, thickening in the region of the cervix, forming a blind cranial base to the atrophied segment. Caudal vagina, uterine tubes and ovaries did not present significant alterations, with corpus luteum in both ovaries, inferring occurrence of estrous cycle.
