Lymphocytic colitis
The characteristic feature of LC is an infiltration by lymphocytes into the colonic epithelium. Collagenous colitis (CC) shares this feature but additionally shows a distinctive thickening of the subepithelial collagen table. LC and CC have been suggested to represent different phases of a single pathophysiologic process, with LC possibly being a precursor or earlier phase of CC; however, this has not been proven.
