Poster Abstract

• Duodenal polyps are a group of polyps that are fairly uncommon to find on endoscopic evaluation (1).

• They are histologically classified according to mucin phenotype into intestinal and gastric subtypes; the intestinal-type polyps are morphologically subdivided into tubular and tubulovillous adenomas (2)

• We present a case of a 76-year-old male with recurrent hematemesis who was found to have an intestinal-type pedunculated tubulovillous adenoma (TVA) in the descending duodenum • An isolated occurrence of non-ampullary sporadic duodenal adenomas (SDA)’s are a rare finding and presentation as an upper GI hemorrhage is extremely uncommon (3)

• Furthermore, our patient’s polyp was pedunculated which is atypical because most SDA’s are morphologically flat or sessile (4)

• The purpose of this case is to present a rare cause of upper gastrointestinal bleeding and to depict characteristics of an isolated duodenal TVA and its treatment options.

A Rare Manifestation of a Bleeding Tubulovillous Duodenal Polyp Presenting as an Upper Gastrointestinal Hemorrhage

• Duodenal polyps are a group of polyps that are fairly uncommon to find on endoscopic evaluation (1).
