Benign tumors of the duodenum are relatively infrequent and are not easy to discover because of nonspecific symptoms. The polypoid lesions of the doudenum have a propensity for causing occult gastrointestinal bleeding, obstruction and intussusception and do have some possibility of being malignant. Therefore, when possible, these lesions should be removed and examined histologically. We experienced five cases of Brunners gland adenoma in the duodenal bulb. The patients complained of epigastric discomfort, nausea, vomiting and tarry stool. The upper gastrointestinal radiography and endoscopy revealed round to oval shaped pedunculated polyp in the duodenum in all cases. We did endoscopic duodenal polypectomy without complications.
