Successful Management of Severe Recalcitrant Pemphigus Vulgaris with Lenalidomide.

Pemphigus variants are treated with immunosuppressives and immunomodulators, but often, clinical remission is challenging. We report a case of pemphigus vulgaris (PV) with involvement of skin, oral mucosa, and esophagus, which failed to respond to commonly used drugs but showed a good response to lenalidomide.
