Lichen Sclerosus is an uncommon condition that creates patchy, white skin that appears thinner than normal.  It usually affects the genital or anal areas. Anyone can get lichen sclerosus but post-menopausal women are much higher risk. 

Patients complain of itch and redness, usually in the genital area.  Sexual intercourse can be very difficult or impossible.  Your Doctor can prescribe creams or ointments which will relieve symptoms, that help return a more normal appearance to the skin and decrease the tendency for scarring. 

However, the condition does tend to recur, so long-term follow up care is needed. Patients with lichen sclerosis have an increase risk of developing squamous cell carcinoma and should be under the long-term surveillance of the Skin specialist/Gynaecologist.
