 In this article, we described the advances in endoscopic diagnosis of ulcerative colitis-associated tumor(UCAN). Specifically, we discussed the current status and issues regarding detection, qualitative diagnosis, and degree of atypia or invasion depth diagnosis. For the presence diagnosis, it is important to detect flat dysplasia. Regional redness has also been reported to be a useful finding. Moreover, dye chromoendoscopy is beneficial for surveillance. Recently, the efficacy of image-enhanced endoscopy, such as NBI/BLI, and new image-enhanced endoscopy, such as LCI/TXI, has been reported. Regarding characterization diagnosis, the existing magnifying endoscopic diagnosis has challenges in terms of differentiating neoplastic from non-neoplastic lesions, and new surface structure patterns have recently been reported. The invasion depth diagnosis is still a challenge, but a finding of deep invasion is considered a highly specific finding.
