Lichen sclerosus, usually appearing in the dermatologic literature under the names of lichen sclerosus et atrophicus, balanitis xerotica obliterans, and kraurosis vulvae, is an inflammatory disease with a multifactorial origin. A past association of lichen sclerosus and genital squamous cell carcinoma is not as close as once thought. Once considered primarily a surgical problem, especially when the genitals were involved, lichen sclerosus will respond to a variety of systemic and topical therapies.

The majority of hand dermatitis occurring in this group is due to irritant contact dermatitis; the frequency of allergic contact dermatitis is very low (0.67%). None had contact urticaria.
