OverviewLichen planus is an intensely itchy (pruritic) inflammatory lesion of the skin. The lesions are generally violaceous (red-purple), slightly raised bumps (papules) with fine scales. The papules may run together (coalesce) to form a larger raised surface (plaque). This is a condition usually seen in adults, although it can occur in children.
