Immunohistochemical evaluation of the effect of acitretin and systemic steroid treatments on Ki-67, Bcl-2, and COX-2 levels in cutaneous lichen planus patients.

With this study in cutaneous lichen planus, prednisolone and acitretin treatments reduced Bcl-2 and Ki-67 levels and did not effect COX-2 levels. It should be clarified whether these results can be obtained with any treatment effective in cutaneous lichen planus.
