Uterine papillary adenocarcinoma in a Pit-bull dog

Abstract

The uterus of an 18 month old Pit-bull removed during ovariohysterectomy formed the material of this study. Macroscopically, the uterus was whitish in color and elastic in consistency, the uterine horns were 15 cm long with a 1 cm of diameter. On cut section uterine mucosa showed variable sized cysts and was filled with a yellowish white mucus. Microscopical evaluation demonstrated a proliferation of the glandular component of the endometrium and a migration of these glands into the myometrium. Glands located in both the endometrium and the myometrium formed large cystic structures. The atypical glandular epithelium showed papillary projections into the cystic spaces. The tumor was diagnosed as uterine adenocarcinoma, an extremely rare canine tumor, especially in young dogs.
