A Case of Linear Lichen Planus Associated with Cicatrical Alopecia and Vitiligo / 대한피부과학회지

Lichen planus is a papulosquamous disorder that has numerous clinical variants. Linear lichen-planus (LLP), a variant of lichen planus, consists of itchy linearly distributed, violaceous papules on the extremities. In lichen planopilaris (LPP), involvement of the hair follicles can induce a form of cicatrical alopecia. Half of the LPP cases have or develop characteristic skin or mucosal involvement of lichen planus. Vitiligo is a chronic disorder characterized by a marked absence of melanocytes and melanin in the epidermis. The coexistence of vitiligo and lichen planus is rare. However, this association is of interest because a cell-mediated immune reaction is thought to play a central role in the pathogenesis of both diseases. We report on a 32-year-old woman affected with LLP, accompanied by cicatrical alopecia and vitiligo.
