A representative case of SCC in EC3: A Endoscopic view by WLI. Redness and a slightly depressed lesion (yellow arrows) can be seen. B Endoscopic view by NBI. A brownish area with background coloration (white arrows) can be seen. C Endocytoscopic image of the lesion. EC classification was graded to be 3 by the endoscopist. D The resected specimen histologically revealed SCC (red line). E Photomicrograph of the resected specimen shows carcinoma in situ (H&E, orig. mag. × 40).
