title: Extragenital bullous lichen sclerosus.
abstract: Lichen sclerosus is an inflammatory skin condition characterized by inflammation of the papillary dermis that leads to white scarlike plaques. It occurs classically in the genitals but also has extragenital manifestations with a variety of clinical presentations including a bullous variant. The purpose of this review is to characterize extragenital bullous lichen sclerosus, suggest that it may be more common than dermatologists realize, and discuss treatment of both routine and recalcitrant cases.
