title: [A case of Brunner's gland hamartoma as a cause of digestive tract hemorrhage].
abstract: A twenty six year old woman was admitted suffering an anemia syndrome, postprandial vomiting and intermittent melena of six months evolution. The hemoglobin was 3.5 g/dL: an endoscopy detected a large tumor in the duodenum with a 90% obstruction of the lumen. A biopsy reported an erosive, acute and chronic duodenitis. Subsequently a surgical exploration with duodenotomy showed a large nodular polyp attached to a stalk that was removed: a hamartomatous polyp of Brunner's glands was reported. It coursed with gastrointestinal bleeding and symptoms of duodenal obstruction, which are two of the most common symptoms of this rare tumor.
