[Case of a leiomyoma in the uterus and cervix of a sheep].
Morphologic studies were carried out on the genital organs (uterus, cervix, oviducts, and ovaries) of a 3-year-old sterile sheep. A gross lesion was found in the region of the uterine bifurcation, consisting of a tumor-like formation of a 3 cm dia, pale gray cross-section surface, and elastic to hard consistence. Histologically, proliferation was seen of the smooth-muscle cells in various directions within the uterus and cervix. It was demonstrated to be a primary leiomyoma, originating from the myometrium. Its gross and microscopic appearance resembled the leiomyomas found in the remaining parts of the body of other mammals and man. The endometrium presented desquamation of the protective epithelium, necrobiosis of the uterine glands, activation of the local cell elements, and oedema of the stroma. There were persisting corpora lutea, atretic follicles, and sclerotic changes in the ovaries. No changes were found in the oviducts.
