　A 76-year-old man was admitted to our hospital, complaining of anorexia from which he had suffered for one year. On admission, there were no abnormal findings in physical examination and laboratory data. Early duodenal cancer was confirmed by x-ray examination, endoscopic examination, and biopsy. We performed subtotal gastrectomy. There was a slightly elevated lesion in the anterior wall of the bulbus. Histology revealed a well-differentiated papillotubular adenocarcinoma in the submucosal layer. No lymphatic metastasis was seen.
