Extragenital Bullous Lichen Sclerosus Treated with Fractional CO(2) Laser (FxCO(2)) and Wet Dressing of Halcinonide Solution: A Case Report

Lichen sclerosis (LS) is an insidious, chronic, relapsing skin disease characterized by atrophic, porcelain-appearing plaques. It usually arises in the anogenital area, but some cases can present in extragenital regions with a variety of presentations, including a bullous variant. Topical corticosteroids are a first-line therapy and are usually the most effective treatment to induce remission of LS. However, there is a subset of patients that does not respond well to topical steroids. Herein, we report an extragenital bullous LS case successfully treated with a fractional CO(2) laser (FxCO(2)) and subsequent wet dressing of halcinonide solution.
