TUMOURS OF FEMALE GENITALIA IN CATTLE SHEEP AND PIGS FOUND IN A BRITISH ABATTOIR SURVEY

A histological survey was made of all neoplasms found in slaughtered cattle, sheep and pigs during one year in 100 abattoirs throughout Great Britain. The specimens collected comprised 302 tumours from cattle, 107 from sheep and 139 from pigs. Twenty female genital tumours were found in cattle, 2 in sheep and 6 in pigs. Ovarian tumours included granulosa-cell tumours, a combined granulosa-cell tumour and teratoma, papillary serous cystadenocarcinomas, mucinous cystadenocarcinomas, an adeno-acanthoma and simple mesenchymal tumours. All specimens from the body of the uterus were mesenchymal tumours, usually of smooth muscle. Squamous carcinomas of the ectocervix and a vaginal fibroma occurred in cattle. The incidence and histological appearances are reported, with reference to the characteristics of human female genital neoplasms. © 1968.
