Abstract
|
|
|
An adenocarcinoid is a mixed tumor comprised of both carcinoid and adenocarcinomatous components that is
commonly found in the esophagus, stomach, duodenum,small bowel and appendix, and is also rarely found in the
large bowel. A 61 year old male visited our institution because of a change in bowel habitus 3 months prior to
the time of his visit. Colonoscopic findings revealed a 2×2 cm round smooth surface mass 7 cm from the anal verge, and an endoscopic ultrasonograph revealed a round hypoechoic mass in the submucosal layer. The mass was resected by endoscopic mucosal resection using a capfitted endoscope. Pathologic analysis of the mass confirmed that it was a composite tumor comprised of carcinoid and adenocarcinomatous components. To the best of our knowledge, this paper is the first case of rectal adenocarcinoid reported in Korea.
