[ Summary ] Duodenal tumors are rare and there is usually little opportunity to observe them in daily medical practice. Duodenal adenomas and carcinomas frequently present an elevated morphology through endoscopic findings and can be detected easily with clear margins. However, it is very difficult to determine whether they are adenomas or carcinomas even if chromoendoscopy and NBI magnification are applied to the diagnostic process. There are no established criteria for standard treatment or curative resection at the present time. Centralization is considered to be important for the development of further investigation. If a duodenal tumor is detected or suspected, it is recommended to refer the patient to an advanced institution immediately.
