What are the causes for Lichen Sclerosus?

The underlying cause of lichen sclerosus is not fully understood. The condition may be due to genetic, hormonal, irritant and/or infectious factors (or a combination of these factors). It is believed to relate to an autoimmune process, in which antibodies mistakenly attack a component of the skin. Other autoimmune conditions are reported to occur more frequently than expected in people with lichen sclerosus. In some cases, lichen sclerosus appears on skin that has been damaged or scarred from previous injury or trauma.

What are the symptoms for Lichen Sclerosus?

The symptoms are the same in children and adults. Early in the disease, small, subtle white spots appear. These areas are usually slightly shiny and smooth. As time goes on, the spots develop into bigger patches, and the skin surface becomes thinned and crinkled. As a result, the skin tears easily, and bright red or purple discoloration from bleeding inside the skin is common. 

Symptoms vary depending on the area affected. Patients experience different degrees of discomfort. When lichen sclerosus occurs on parts of the body other than the genital area, most often there are no symptoms, other than itching. If the disease is severe, bleeding, tearing, and blistering caused by rubbing or bumping the skin can cause pain.

What are the current treatments for Lichen Sclerosus?

Strong topical steroid creams or ointments reportedly are very helpful for lichen sclerosus, especially when it affects the genital areas. However, the response to this treatment varies. While itching may be relieved within days, it can take weeks or months for the skin's appearance to return to normal.

Other treatments that may be used instead of steroid creams, or in combination with steroid creams, include calcipotriol cream, topical and systemic retinoids (acitretin), and/or systemic steroids.

If the vaginal opening has narrowed, dilators may be needed. In rare cases, surgery is necessary to allow for sexual intercourse. The condition sometimes causes the vaginal opening to narrow or close again after surgery is initially successful.
