INCIDENCE AND PATHOMORPHOLOGY OF UTERINE-TUMORS IN THE COW

A statistical and pathological study on uterine rumours during the exa mination of 1489 female bovines at slaughter was carried out. A 0.4% ( n = 6) incidence of uterine neoplasms, being 50% adenocarcinomas and t he other 50% leiomyomas, was diagnosed. With regard to age groups, rum ours were more frequent in the 11-15-year-old group. Two animals affec ted by adenocarcinoma were not fertile and they had ovarian metastasis that, to the authors' knowledge, has been cited as extremely rare in cows. An ultrastructural study of these carcinomas and their metastasi s was also made. Two leiomyomas were intramural and another one was pe dunculated and subserous located. All leiomyomas showed the features o f old rumours.
