Lichen Sclerosus: Symptoms & Signs

Lichen sclerosus is a skin condition that appears mostly around the genital and anal areas. It is most common in postmenopausal women and is uncommon in children and in men.

Signs and symptoms of lichen sclerosus include skin changes in the genital area, perianal area, or elsewhere on the upper body that include a loss of skin color, with white patches of skin that grow into larger areas, scarring, itching, and thinning and crinkling of the skin. Other associated symptoms of lichen sclerosus can include skin tears, bruises, pain, blistering, and bleeding.

Cause of lichen sclerosus

Physicians do not fully understand the exact cause of lichen sclerosus, but it seems to be related to an overactive immune system and hormonal problems.
