Vulvovaginal erosive lichen planus refractory to topical therapies: What's next? A case report.

A 60-year-old woman was referred for progressive and severe vulvovaginal pain characterized by erosions and Wickham's stria for the past 7 months. Her condition had not responded to oral fluconazole, topical estrogen cream, and topical clobetasol cream. Vulvar and vaginal biopsies were obtained under general anesthesia to verify the diagnosis of erosive lichen planus given the failed response to ultrapotent topical steroids. Tacrolimus cream was added but not tolerated. Oral and cutaneous lesions of lichen planus also developed. In the absence of evidence-based guidelines, three different systemic treatments were administered sequentially (hydroxychloroquine, mycophenolate, and finally cyclosporin) before a satisfactory, well-tolerated, and sustained clinical response was obtained. Topical betamethasone ointment in a taper was continued to assist in sustaining a vulvovaginal response after cyclosporin was discontinued.
