DYNAMICS OF SQUAMOUS CELL CARCINOMA ANTIGEN CONCENTRATION IN PATIENTS WITH LICHEN PLANUS OF THE ORAL MUCOSA

In modern views on the etiopathogenesis of lichen planus (LP), the leading role is given to disturbances in the immune status. The level of cytokines in the oral fluid correlates with the concentration of the squamous cell carcinoma (SCC) antigen. In 80% of patients with the erosive-ulcerative form of LP, with an increase in the SCC level in mixed saliva after treatment, clinical manifestation of the disease was diagnosed after 90 days.
