 It is easy to diagnose an elevated lesion due to gastritis by its ordinary endoscopic findings. In the stomach intestinal metaplasia or the regenerative mucosa of the erosion or ulcer often causes these elevated lesions. Such lesions were often found in the antrum. Some adenoma and hyperplastic elevated lesions are difficult to diagnose differentially from early gastric cancers type Ⅱa. At such times it is very useful to perform magnifing endoscopic examination and find out the fine gastric mucosal pattern (FGMP) . FGMP of malignant lesions resembles the D pattern which can be found also in regenerative hyperplastic mucosa, but it is irregular. If there is erosion or ulceration in the malignant lesion, regenerative mucosa comes to form a special pattern which Ⅰ call malignant regenerative mucosal pattern (MRMP). Sometimes, we can find a newly produced malignant vessel accompanied by a malignant lesion. So, if we focus on these special findings of magnifing endoscopy, we can make a more precise diagnosis about such lesions.
