A rare case of mucinous adenocarcinoma of the duodenal bulb is reported. A 66-year-old woman was admitted to our hospital because of nausea and vomiting, Upper GI series and endoscopic examination revealed a Borrmann 2-like tumor in the duodenal bulb. Histological diagnosis of biopsy specimens was group V. A curative pancreatoduodenectomy was done under the diagnosis of a primary advanced adenocarcinoma of the duodenal bulb. Macroscopically, the tumor was seen on the side of the greater curvature of the duodenal bulb, with a Borrmann 2-like appearance, 4.0×5.0×1.0 cm in size. Histologically, tumor cells, which were well stained by the periodic acid Schiff, occupied most of the submucosal layer. Therefore, we concluded the tumor was a mucinous adenocarcinoma originating in Brunner's glands.
