Paucicellular Lymphocytic Colitis: Is It a Minor Form of Lymphocytic Colitis? A Clinical Pathological and Immunological Study

Abstract

The incidence rate of PLC, identified using objective histological criteria, was higher than those of CC and LC. The lack of expression of CD25+FOXP3+ cells in PLC, in contrast to those seen in both LC and CC, would suggest the existence of different pathophysiological mechanisms and does not support that PLC is a minor form of LC.
