POLYPS OF THE GASTROINTESTINAL TRACT
A polyp, a mass of tissue that arises from the surface and extends into the lumen of the gastrointestinal tract, usually represents an overgrowth of epithelial cells. Polyps can be single or multiple, sporadic or familial, pedunculated (on a stalk) or sessile (flat based), neoplastic or nonneoplastic, as well as benign or malignant. They can also occur virtually anywhere in the gastrointestinal tract. The polyps of greatest importance, however, are those found in the colon, so these will receive primary attention. A simplified classification of colonic polyps is given in Table 41-3. Only the neoplastic polyps and those benign polyps associated with the familial polyposis syndromes will be discussed here.
