Two cases of polypoid adenoma of Brunner glands occurred. One patient had nausea and vomiting, and the other mere epigastric discomfort. One was in the first portion of the duodenum, the other in the second. Both were removed by simple transduodenal excision and the patients did well. It is a relatively rare benign tumor, which may be of hamartomatous origin.
