Incidence and pathomorphology of uterine tumours in the cow.
A statistical and pathological study on uterine tumours during the examination of 1489 female bovines at slaughter was carried out. A 0.4% (n = 6) incidence of uterine neoplasms, being 50% adenocarcinomas and the other 50% leiomyomas, was diagnosed. With regard to age groups, tumours were more frequent in the 11-15-year-old group. Two animals affected by adenocarcinoma were not fertile and they had ovarian metastasis that, to the author's knowledge, has been cited as extremely rare in cows. An ultrastructural study of these carcinomas and their metastasis was also made. Two leiomyomas were intramural and another one was pedunculated and subserous located. All leiomyomas showed the features of old tumours.
