What is lichen sclerosus?
Lichen sclerosus is a benign and progressive skin disease that most often affects the genital area. This chronic skin condition cannot be cured but can be controlled. Lichen sclerosus is marked by itching and pain in the genital area. The skin near the opening of the vagina, called the perineum, becomes thin and inflamed. This skin disorder is common in women after menopause. Lichen sclerosus is uncommon in men and very rare in children. The condition is not contagious.
Lichen sclerosus can develop on any skin surface, but it usually occurs in the perineum. The condition can make the opening of the vagina smaller so that sexual intercourse becomes painful. Blisters and bleeding may also occur.
Lichen sclerosus starts out as small white spots on the skin. These spots are generally shiny and smooth. The spots then grow into larger patches that are thin and crinkled. This thin skin can tear easily and may be accompanied by red or purple bruises. Skin scarring may also occur with lichen sclerosus.
Lichen sclerosus of the genital skin should be treated, as it can cause problems with urination or sex. There is also a very small chance that skin cancer will develop at the site affected by lichen sclerosus. Lichen sclerosus can be treated with topical ointments or creams, and the symptoms should clear up in a few weeks.
Seek prompt medical care if you are being treated for lichen sclerosus and mild symptoms recur or are persistent.
