A Case of Actinic Lichen Planus / 대한피부과학회지

ABSTRACT

Actinic lichen planus is a particular subtype of lichen planus with a distinct photodistribution. This disease has been variously named lichen planus in subtropical countries, such as lichen planus subtropicus annularis, lichen planus tropicus, summertime actinic lichenoid eruption, and lichenoid melanodermatitis. It is a disorder seen most frequently in Africa, the Middle East, and the Indian subcontinent, favoring Asians. This disease presents in the spring or summer and is frequently quiescent during the winter. A 61-year-old man with unusual lichenoid photosensitive eruption is presented. The lesions developed during the late spring, appearing on both dorsa of hands, wrists, and lower legs. We report a case of actinic lichen planus with a review of the literature.
