Type of disease: Rare conditions
Lichen sclerosus is a skin disorder that can affect men, women, or children, but is most common in women. It usually occurs on the vulva (the outer genitalia or sex organ) in women, but sometimes develops on the head of the penis in men. Occasionally, lichen sclerosus is seen on other parts of the body, especially the upper body, breasts, and upper arms. Other names for lichen sclerosus include kraurosis vulvae and hypoplastic dystrophy. Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
