| This adenomatous polyp has a hemorrhagic surface (which is why they may first be detected with stool occult blood screening) and a long narrow stalk. The size of this polyp--above 2 cm--makes the possibility of malignancy more likely, but this polyp proved to be benign. In the endoscopic view on colonoscopy seen below, there is a large pedunculated polyp on a long stalk. |
