Histopathological investigation of ovine intestinal adenomas in Basrah abattoir

Abstract EN

In order to investigate the histopathological features of ovine intestinal adenomas, the study achieved in 27 macroscopically suspected intestinal adenomas of sheep aged between 2-3 years, which diagnosed in Basrah abattoir, the intestines of slaughtered sheep were fixed and processed for light microscopy.

The histopathological results showed multiple stages of neoplastic differentiation, mainly circumscribed areas suggesting adenomatous form by proliferating mucous glands in sub mucosal region of colon of varying sizes, some of which with clear proliferating hypertrophic and hyperplastic epithelial lining with area of angiogenesis and hemorrhage around them.

Morever, the results showed circumscribed areas of adenomatous glandular structures enclosed by superficial mucosal epithelium and in sub mucosal region of rectum.

It had been concluded that the ovine intestinal adenomas showed a degree of differentiation in mid aged sheep (2-3 years old aged) that may resembles other adenomatous intestinal lesions reported in more older age of others domestic animals.
