[Endoscopic resection of hamartoma of the duodenum]

Abstract

Duodenal tumors are rare and, Brunner's glands proliferation encompass a small percent. The duodenal hamartoma generally has a polypoid configuration. It can present as two clinical conditions; bleeding and obstruction, even though most of the time it is asymptomatic or presents non specific gastrointestinal symptoms. Another possibility is the association with polypoid lesions of the large bowel, as it happens in Peutz Jeghers and Gardner's syndrome. Malignant transformation is exceedingly rare. Endoscopy has an important role, not only to ensure proper diagnosis, but also as a valuable therapeutic option.
