Lichen planus and lichen-planus-like reactions. 1986

R Graham-Brown

Lichen planus is a common disorder affecting the skin, oral and genital epithelium, hair and nails. It is said to account for approximately 1% of new patient referrals to skin clinics (Samman, 1979). It is, therefore, an important entity to the dermatologist. However, lichen planus and lichen-planus-like reactions have been described in a number of clinical situations which may bring them first to the attention of doctors practising in other specialties.

UI	MeSH Term	Description	Entries
D008010	Lichen Planus	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.	Cutaneous Lichen Planus,Lichen Planopilaris,Lichen Ruber Planus,Mucosal Lichen Planus,Lichen Rubra Planus,Lichen Planus, Cutaneous,Lichen Planus, Mucosal,Planopilaris, Lichen
