Lichen sclerosus (LS) is a chronic inflammatory dermatosis that is characterized by the presence of white papules and atrophic plaques. We describe 4 women with asymptomatic whitish papules and atrophic plaques at various locations on the body. Histopathologic examination of the lesions showed atrophy of the epidermis, follicular plugging, and a lymphocytic infiltrate. In all 4 cases, dermoscopy showed a whitish plaque with comedolike openings in the center of the lesion, and a diagnosis of extragenital LS was made.
