Abstract

Colonic muco-submucosal elongated polyp is a rare entity (0.39% in an endoscopic polypectomy series). It is an elongated drumstick-shaped lesion characterized by oedematous, loose connective tissue with a dense submucosal layer showing dilation of blood and lymphatic vessels. First described as a polypoid lesion associated with diverticular disease of the sigmoid colon, it was histologically characterized as a separate entity by Kelly in 1991. In that study, the author reported eight cases in which a red or brown mucosal protrusion or polyp were associated with diverticular disease, and described the syndrome as "polypoid prolapsing mucosal folds in diverticular disease". In 1994, Matake et al. described a new entity defined as colonic muco-submucosal elongated polyp. Herein, we describe another case in a 77-year-old woman with abdominal pain, followed by a review of the literature.
