 The colonic IIc is histologically defined as a superficially but absolutely depressed type neoplastic lesion of cancer or adenoma, and the depressed lesional floor is lower than the surrounding intact mucosal surface.

 It is required to differentiate it from the lesion of relative depression which histologically shows the depressed lesional bed being higher than the surrounding normal mucosal surface.

 When the colonic lesion is endoscopically suspected to have well-demarcated absolute depression, it is denoted as IIc or IIc+IIa. When suspected to be relative depression, it is denoted as IIa+IIc.
