Definition
=========================================================================

● Mass protruding above the colonic mucosa into lumen of gut

Terminology
=========================================================================

● Sessile: no stalk
● Pedunculated: with stalk, may be due to traction on the mass
● Hamartomatous / inflammatory: polyp due to abnormal maturation or architecture (hamartomatous), or inflammation
● Neoplastic / adenomatous: polyp due to proliferation and dysplasia of epithelium

Clinical
=========================================================================

● Polypoid lesions may also be due to mucosal or submucosal tumors
● Clinical impression correlates poorly with neoplasia (J Gastroenterol Hepatol 2006;21:563)
● Appelman recommends calling “benign mucosal polyp” unless (a) diagnosis is adenoma [the only diagnosis that causes clinicians to do anything different] or (b) you can classify it within 30 seconds
