MeSH Heading: Lichen Planus
Tree Number(s): C17.800.859.475.560
Unique ID: D008010
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D008010
Annotation: a skin disease; sometimes called simply "lichen": check text; lichen planus atrophicus: index here & do not confuse with LICHEN SCLEROSUS ET ATROPHICUS
Scope Note: An inflammatory, pruritic disease of the skin and mucous membranes, which can be either generalized or localized. It is characterized by distinctive purplish, flat-topped papules having a predilection for the trunk and flexor surfaces. The lesions may be discrete or coalesce to form plaques. Histologically, there is a saw-tooth pattern of epidermal hyperplasia and vacuolar alteration of the basal layer of the epidermis along with an intense upper dermal inflammatory infiltrate composed predominantly of T-cells. Etiology is unknown.
