Ask a question


Lichen sclerosus is a disease of the skin and mucous membranes. It is a chronic condition that primarily affects the genitals and causes itching or pain. It comes in the form of red patches topped with small, whitish lesions, and is frequently localized on the glans or the penis in men, and at the vulva or regions near the labia in women. Lichen sclerosus is treated by applying creams containing corticosteroids. These lesions are not contagious but can be recurring.
