 So-called“serrated lesions”included hyperplasic lesion, sessile serrated adenoma/polyp, traditional serrated adenoma, adenoma with serration, etc. Recently, a kind of“serrated lesion”has been reported to be the precursors of colorectal cancer with microsatellite instability although little is known about endoscopic findings of such lesions. On the other hand, this type of“serrated lesion”is currently recognized even though endoscopic diagnosis of“serrated lesions”has not yet been established. In the present study, we recognized several surface micro-structures of “serrated lesions”by using magnifying colonoscopy, and compared them with pathological diagnosis. As a result, we found that endoscopic findings were correlated with pathological diagnosis during the tumorigenesis of colorectal cancer. Further study will be needed to establish endoscopic diagnosis for“serrated lesions”by magnifying colonoscopy.
