We present a 84 year old male with a history of chronic diarrhea and megaloblastic anemia. A week before his hospitalization had nausea and vomit. An upper endoscopy showed a submucosa elevated lesion of 40 mm in the duodenum bulb, the biopsy was not contributory. The diarrhea and megaloblastic anemia resolved with cianocobalamina and folic acid, later the submucosal lesion was removed by surgery. The histological study of the specimen revealed a Brunner's glands tumor. The Brunner's glands tumor, also known as brunneroma, is a rare benign duodenum's lesion; it could be incidentally discover during an endoscopy and sometimes it cause of bleeding or obstruction. There is controversy if this tumor is an hamartoma or a true adenoma.
