A Case of Linear Lichen Planus / 대한피부과학회지

ABSTRACT

Linear lichen planus, a rare variant of lichen planus, accounts for 0.24-0.62% of all patients with lichen planus. Clinically, it consists of itchy linear-distributed violaceous papules, usually last 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 infiltration with hyperkeratosis, focal hypergranulosis, acanthosis, exocytosis and the presence of Civatte body. We report a 46-year-old woman showing typical clinical and histological features of linear lichen planus without pruritus.
