Does lichen sclerosus cause white patches on skin?
Yes, white patches on the vulval, perianal, or genital skin are a classic feature of lichen sclerosus. These patches are usually smooth, shiny, and may gradually increase in size.
Detailed Medical Explanation
The white patches (leukoderma) are caused by thinning of the top layers of the skin and changes in the connective tissue beneath. Over time, these areas may become thickened, wrinkled, or fragile, and may crack or bleed. The patches are usually not painful but are often associated with itching.

Clinical Context
White patches are a hallmark of lichen sclerosus and should always prompt specialist evaluation. Our clinic can provide diagnosis, education, and ongoing support: Vulval Skin Conditions Clinic.
Evidence-Based Approaches
Topical steroids are the most effective way to reduce white patches and prevent disease progression. For more, see NICE BNF.
