Abstract

Tumours of the intesnne in cattte and other domestic animals are rarely encountered Carcinomas of the rumen and small intestines have been observed, but the large mtesnnes mcludlng Ihe rectum are seldom affected. Squamous cell carcinoma of the anus ano rectum was observed In an adult snes.en Cow, and this was confirmed on both gross and histolological examination. A twenty year survey of neoplasms of the Intestines In cattle from post mortem reports In the Vet. Pathology Department University of Nairobi, yielded only other case of squamous cell carcinoma of the anus and perineum amidst other tumours. The low incidence-of this and other tumours of the intestine in cattle emphasises their uncommon nature.
