Print: What causes lichen sclerosus?
Doctors don’t know the exact cause of lichen sclerosus. An overactive immune system, hormone problems, injury or a family history of lichen sclerosus may increase your risk of getting it. Lichen sclerosus is not contagious. You can’t catch it from or pass it to someone else.
