A, Case 1: Paris Classification 02A lesion seen with NBI. Nodular area at 41 to 42 cm at the 8 to 12 o'clock position with loss and irregularity of villous and vascular pattern. B, The same lesion seen with WLE. Cautery marks from tip of snare are used to demarcate the lesion prior to EMR. Submucosal cancer was found in the EMR specimen.

A, Case 2: Paris Classification 02A lesion seen with WLE. A nodular area is seen at 40 to 41 cm at the 9 to 1 o'clock position (rotated in this image) demarcated for EMR. B, The same lesion seen on closer inspection with NBI shows irregular mucosal pattern. EMR of this lesion found submucosal cancer.

A, Case 3: Paris Classification 02C lesion seen on WLE. Diffusely abnormal mucosa at 32 to 34.5 cm at the 11 to 5 o'clock position with minor depression and slight nodularity. There is patchy superficial ulceration and slough over this. B, The mucosal and vascular patterns are irregular and indistinct in areas on narrow-band imaging. Submucosal cancer was found following EMR of this lesion.
