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.
