Lichen sclerosus (LIE-kun skluh-ROW-sus) is an uncommon condition that creates patchy, white skin that appears thinner than normal. It usually affects the genital and anal areas.
Anyone can get lichen sclerosus but postmenopausal women are at higher risk.
Your doctor can suggest treatment with creams or ointments that help return a more normal appearance to your skin and decrease the tendency for scarring. The condition does tend to recur, so long-term follow-up care may be needed. Rarely, lichen sclerosus improves without treatment.
