Oral lichen planus: therapy and phenotype

Lichen planus (LP) is a mucocutaneous disease of chronic inflammatory nature. Although many therapeutic options are available, none are curative. The aim of this article was to describe a therapeutic algorithm that take into consideration the clinical futures of oral LP (OLP).Patients affected by symptomatic OLP were enrolled into three groups to receive cyclosporine mouthwash, retinoic acid lotion 0.05%, and autologous platelet-rich plasma (PRP) gel in the treatment of reticular, plaque-like, and erosive-type respectively. The products were applied as follows: retinoic acid BID for 8 weeks, cyclosporine mouthwash OD for 8 weeks, PRP once a week for 8 weeks. Patients were assessed at 2, 4, 8, and 12 weeks. Improvement was evaluated as complete response, partial response and no response.A total of 20 Caucasian patients, 8 male and 12 female, mean age 56 years (range 40-74) concluded the study. Seven patients showed a complete response, 7 patients a partial response, and 6 patients no response.We propose a therapeutic algorithm that take into consideration the clinical features and symptoms of OLP. Long-term experience on larger series of cases are necessary to confirm our data.
