Use of topical cyclosporin in oral pemphigus

The use of systemic cyclosporin in the treatment of pemphigus is well recognized. Oral lesions in pemphigus vulgaris are common but can be very difficult to treat. Short use of topical cyclosporin has been reported in a few cases of oral pemphigus. We report the successful use of topical cyclosporin for several years in a patient with debilitating oral pemphigus in whom systemic immunosuppressive agents and topical steroids had been ineffective and in whom cyclosporin was used not only to induce but also to maintain remission.
