Guidelines for the follow-up of women with vulvar lichen sclerosus in specialist clinics.

It is recommended that women with vulvar lichen sclerosus be followed in specialist clinics where difficulty exists with symptom control or where there is clinical evidence of localized skin thickening. Follow-up is also recommended for women who have previously been treated for squamous cell carcinoma of the vulva (arising in lichen sclerosus or vulvar intraepithelial neoplasia) or where the pathologist expresses concern and is unable to make a definitive diagnosis of differentiated vulvar intraepithelial neoplasia.
