title: Imiquimod use in the genital area and development of lichen sclerosus and lichen planus.
abstract: Imiquimod has immune-stimulant properties that can precipitate autoimmune conditions like eczema, psoriasis and lichenoid conditions. We report two cases here where imiquimod induced florid lichen sclerosus in one patient and lichen planus in another. In both patients the condition was so aggressive and unresponsive to steroid treatment that circumcision was necessary.
