Lichen sclerosus is a skin condition that appears as white patches. It is most commonly affects the skin around the genital and anal areas of the body, where it can cause pain and itching. However, it can also be found on other areas of the body, including the upper body, arms, breasts, buttocks, and outer thighs.
Lichen sclerosus occurs in boys, girls, and adult men and women. However, it is most commonly seen in females. Although it can occur at any age, it is typically seen before puberty (before girls start having menstrual periods) or after menopause (after women stop having periods). It is most frequently seen in postmenopausal women.
