Primary carcinoma of the duodenal bulb is very rare. We report herein on a case involving a patient with early duodenal bulb carcinoma accompanied by gastrointestinal stromal tumor (GIST) of the stomach. A 74-year-old woman was found by computed tomography (CT) to have a gastric submucosal tumor. Endoscopic examination revealed a submucosal tumor of the stomach, and a large, superficially elevated lesion at the duodenal bulb. Gastric wedge resection and distal gastrectomy were performed. Reconstruction was carried out according to the Billroth II method. Histologically, the submucosal tumor was diagnosed as gastrointestinal stromal tumor (GIST), and the duodenal tumor was diagnosed as well-differentiated tubular adenocarcinoma in tubulo-villous adenoma. The patient recovered uneventfully, and was healthy, having had no recurrence, 3 years and 6 months after surgery. To the best of our knowledge, the superficially elevated bulb carcinoma in our case may be larger than any other previously reported ones.
