Giant gastric tubulovillous adenoma : A rare upper gastrointestinal bleeding

Polyps are defined as proliferative lesions of the gas- trointestinal mucosa growing into the lumen (1). Gastric polyps are typically asymptomatic. These lesions can be seen during approximately 2-6% of endoscopic proce- dures (2). Rarely adenomas lead to bleeding, and become symptomatic with anemia, abdominal pain and gastric outlet obstruction. Hyperplastic polyps, the most com- monly identified histological type, is considered non- neoplastic. The most common types of hyperplastic pol- yps in the stomach are fundic gland and adenomatous polyps (3). Adenomatous polyps of the stomach consti- tute 8% to 10 of all polyps and have three different sub- types : tubular, villous and tubulovillous polyps. Villous and tubulovillous adenomas have a high risk of develop- ing malignancy. AlsO. the risk of malignancy increases proportionally to the diameter of the polyp.
