ALMEIDA, M.V.D. et al. Segmental aplasia of the uterine body in a mongrel bitch: a case report. Arq. Bras. Med. Vet. Zootec. [online]. 2010, vol.62, n.4, pp. 797-800. ISSN 0102-0935.  http://dx.doi.org/10.1590/S0102-09352010000400005.

A case of partial segmental aplasia of the uterine body in a sexually mature mongrel bitch in anestrous phase and normal clinical condition is reported. At necropsy, no changes in the genital organs were observed with the exception of the uterine body that had a segmental (2mm in length) decrease in diameter in its medial-caudal portion, with absence of lumen and hydrometra in the cranial portion of the uterine body and uterine horns. Histopathologic evaluation indicated reduction in thickness of the whole uterine body at the site of stenosis, with all layers preserved including perimetrium, myometrium, and endometrium, but with the absence of a lumen. The walls of the uterine horns were thin and there was a marked decrease in the number of endometrial glands. There were several follicles on different stages of development and corpora lutea in regression, indicating that the bitch had normal cyclic activity.
