chronic photodermatitis with sensitivity to a broad spectrum of radiation, usually occurring in older men; it first occurs on sun-exposed areas as a scaly pruritic erythema, often spreading and leading to thick plaques, furrows, and leonine facies. Lesions are characterized histologically by a polymorphous dermal infiltrate that resembles lymphoma.
