TREATMENT OF SEVERE LICHEN-PLANUS WITH CYCLOSPORINE

Two patients with severe chronic lichen planus were successfully treated with oral cyclosporine (6 mg/kg/day). A response was noted within 4 weeks, and complete clearing was achieved after 8 weeks of treatment. No significant adverse effect was noted. The patients have remained in remission 3 and 10 months after therapy, respectively. Clinical improvement was accompanied by significant reduction in the T cell infiltrate in the skin. Abnormal expression of keratinocyte intercellular adhesion molecule-1 (ICAM-1), which was present before therapy, became undetectable after 1 week of cyclosporine therapy, before any significant clinical and histologic change. © 1989, American Academy of Dermatology, Inc..
