Extragenital lichen sclerosus successfully treated by topical maxacalcitol/betamethasone butyrate propionate.

Lichen sclerosus (LS) is a benign chronic inflammatory skin disorder affecting the anogenital and extragenital areas, and an autoimmune disease characterized by autoreactive T cells. Clinically and histopathologically, LS and scleroderma are similar.(1) Patients are usually asymptomatic or may present with slightly itchy, white papules with progressive development of parchment-like skin. Topical corticosteroids are recommended as first-line treatment; most patients are initially treated with potent topical corticosteroids.
