Diseases of the canine uterus.

Lesions most commonly found in the canine and feline uteri fall primarily into two categories: (i) abnormalities of endometrial growth and repair and (ii) uterine infections with associated endometritis. Neoplastic conditions of the tubular genitalia of the bitch, with the possible exception of leiomyomas (tumours that arise from smooth muscle cells), are uncommon. Congenital lesions involving the uterus are relatively rare. The primary object of this paper is to provide a summary of the most common uterine lesions found in the canine and feline uterus using a series of images that underscore the most prominent and important gross diagnostic features of each.
