 In this study, we aimed to investigate the correlation between the findings of magnifying endoscopy with narrow band imaging and the histological findings of tumor-like lesions and diffuse duodenal lesions with white villi. The colors of diffuse duodenal lesions with white villi are determined by lymph flow stagnation and the presence of many foamy macrophages and lipid droplets in the lamina propria. In such cases, because microvasculature can be detected on the surface of the white villi, we concluded that magnifying endoscopy facilitates the differential diagnosis of diffuse duodenal lesions with white villi and WOS(white opaque substance)in intestinal-type adenoma. Although the endoscopic diagnosis of tumor-like lesions with islands of typical gastric area on the surface is comparatively easy, tumor-like lesions sometimes require a differential diagnosis with respect to other neoplastic tumors. Therefore, careful examination and analysis of correlations between endoscopic findings, such as microvasculature and the shape of villi, and histological findings may be useful for the endoscopic differential diagnosis of duodenal non-neoplastic lesions.
