Lichen Planus (C0023646)

Definition (NCI) A chronic, recurrent, pruritic inflammatory disorder of unknown etiology that affects the skin and mucus membranes. It presents with rashes and papules that tend to resolve spontaneously. It may be associated with hepatitis C. Certain drugs that contain arsenic or bismuth are associated with reactions mimicking lichen planus.
Definition (MSH) 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.
Definition (CSP) inflammatory, pruritic disease of the skin and mucous membranes, which can be either generalized or localized; characterized by distinctive purplish, flat-topped papules having a predilection for the trunk and flexor surfaces; lesions may be discrete or coalesce to form plaques.

Lichen Planus, Oral (C0206139)

Definition (NCI) A chronic, autoimmune inflammatory condition of the mucous membranes in the oral cavity that affects approximately two percent of the population and is most often seen in middle aged women. It is characterized by white, lacy patches; red, swollen tissue; papules and plaques; or open sores. The lesions are typically bilateral.
Definition (MSH) Oral lesions accompanying cutaneous lichen planus or often occurring alone. The buccal mucosa, lips, gingivae, floor of the mouth, and palate are usually affected (in a descending order of frequency). Typically, oral lesions consist of radiating white or gray, velvety, threadlike lines, arranged in a reticular pattern, at the intersection of which there may be minute, white, elevated dots or streaks (Wickham's striae).
