Angiogenesis of oral lichen planus: a possible pathogenetic mechanism.

Objective: Oral Lichen Planus (OLP) is a chronic inflammatory disease with an autoimmune inflammatory pathogenesis. The aim of the research is to compare the vascular endothelial growth factor (VEGF) and adhesion of molecules in the biopsy samples of patients affected by OLP, in order to research the presence of the angiogenetic phenomenon and to understand its pathogenetic mechanism. Materials and Methods: Thirty OLP patients and thirty healthy subjects were enrolled in a study. The immunohistochemical analysis of the VEGF and vascularendothelial adhesion molecules was carried out by means of primary antibodies and anti-CD34, anti-VEGF, antiCD106 antigen (VCAM-1) and anti-CD54 antigen (ICA…
