Lichen sclerosus (LIE-kun skluh-ROW-sus) is an uncommon condition that creates patchy, white skin that's thinner than normal. Lichen sclerosus can affect skin anywhere on your body. But it most often involves skin of the vulva, foreskin of the penis or skin around the anus.

Anyone can get lichen sclerosus but postmenopausal women have a high risk.

Sometimes lichen sclerosus improves on its own, and you won't need any treatment. If you do need treatment, your doctor can suggest options to return a more normal appearance to your skin and decrease the tendency for scarring.
