One Case of Linear Lichen Planus / 대한피부과학회지

ABSTRACT

Linear lichen planus, a variant of lichen planus, accounts for 0.24-0.62% of all patients with lichen planus. Clinically, it consists of itchy linearly distributed violaceous papules, usually lasts for more than 1 year and the mucous membranes may also be affected. This disorder shows the same histologic findings of lichen planus, which is characterized by a band like dermal inflammatory cell infiltration with hyperkeratosis, focal hypergranulosis, acanthosis, excytosis and the presence of Civatte body. We report a 66-year-old man showing typical clinical and histological features of linear lichen planus with pruritus.
