We have experienced 3 cases of early carcinoma of the duodenal bulb. Case 1: A 63-year-old male who had been operated on because of rectal cancer complained of epigastralgia. An upper gastrointestinal (GI) series and endoscopic examination showed elevated lesions in the duodenal bulb and the antrum of the stomach. Carcinoma was strongly suspected from the biopsy specimens of the duodenal bulb. Gastrectomy, partial duodenectomy and lymph node dissection were performed. Histological examination revealed papillotubular adenocarcinoma located within the mucosa of the duodenal bulb and the stomach. Case 2: A 57-year-old female with no complaints was recommended to have a further precise examination after an upper GI series. An upper GI series and endoscopic examination showed an elevated lesion in the duodenal bulb. The biopsy specimens showed adenocarcinoma. Gastrectomy, partial duodenectomy and lymph node dissection were performed. Histological node dissection were performed. Histological examination revealed papillotubular adenocarcinoma located within the mucosa. Case 3: A 78-year-old male with no complaints was recommended to have a further precise examination of the duodenum after an upper GI series. An upper GI series and endoscopic examination showed an elevated lesion in the bulb and the 2nd portion of the duodenum. The tumor was 2 cm in diameter. The biopsy specimens showed adenocarcinoma. Gastrectomy, partial duodenectomy and lymph node dissection were performed. Histological examination revealed papillotubular adenocarcinoma located within the mucosa and submucosa without lymph node metastasis.
