 We have mainly explained the basics and main point of magnifying chromoendoscopic findings. It is important to understand the composition of pits and epithelial cells from an anatomical viewpoint when learning pit pattern diagnosis. Therefore, we must be able to identify the presence of an innominate groove in the mucosal epithelium and not confuse it with pit findings when using the contrast method with indigocarmine. When the crystal violet staining method is used, it is important to differentiate which mechanisms that often result in poor staining are caused from the following:(1)exposure of submucosal invasive cancer or desmoplastic reaction,(2)mucous coating(mucus cap), and(3)physical injury to the mucosal epithelium. For this purpose, it is important to identify whether there are irregular pits around the poorly stained area or continuity of pits. This can help us better understand the pit pattern classification by basic recognition.
