 This study aimed to investigate the endoscopic characteristics of IN(intraepithelial neoplasia). Of the 204 cases treated by ESD(endoscopic submucosal dissection)for SCC(squamous cell carcinoma)from December 2018 to November 2021, Twenty-two cases with twenty-four IN cases were enrolled in this retrospective study. The lesions were divided into three groups as follows:Group 1:No findings by WLI and NBI, and weakly stained by iodine ; Group 2:Reddish color by WLI or Brownish color by NBI, and Weakly stained by iodine ; and Group 3:No finding by WLI and NBI, and well stained by iodine. Groups 1, 2, and 3 were 20 cases with 22 lesions(92%), 1 case with 1 lesion(4%), and 1 case with 1 lesion(4%), respectively. All the cases in groups 1 and 2 were 0-IIb and were detectable because they stained weakly by iodine. On the other hand, a case in group 3 was stained by iodine, but was found by chance because it was partially elevated.

 Group 1 accounted 92% of IN cases. All 18 cases that showed PCS(pink color sign)/MSS(metallic silver sign)negative were IN. Therefore, PCS/MSS negative is a characteristic findings of IN. On the other hand, 4 cases of PCS/MSS positive cases were also IN. However, all 4 cases showed Kumagai classification Type 2 by ECS(endocytoscopy system). Therefore, it was suggested that ECS may contribute to the differential diagnosis between IN and SCC in case of PCS/MSS positivity.
