 The differential diagnoses of upper gastrointestinal hemorrhagic diseases were summarized in this article. When we find a hemorrhagic lesion, we should wash the lesion and observe it in detail. The hemorrhagic diseases include a lot of malignant diseases, so accurate differential diagnosis is required. Epithelial neoplastic lesions are frequently accompanied by demarcated mucosal lesions, so we should carefully look for such findings. Essential findings of ulcerative and depressed lesions are their shape, surface, edge and circumference. Important findings of protruding lesions are shape of the border, surface and circumference. Moreover, magnifying endoscopic findings of irregular pit and vascular pattern were useful for differential diagnoses. Systemic work up is essential for differential diagnosis of duodenal lesions because there are many kinds of systemic disease in the duodenum.
