Chronic actinic dermatitis (CAD) is a chronic immune-mediated photo-dermatosis causing pruritic eczematous lesions, infiltrated lichenified papules,and plaques on sunexposed skin. It commonly affects elderly males who are chronically exposed to sunlight. The photosensitivity is mostly to ultraviolet (UV) B wavelengths and less frequently to ultraviolet (UV)A and visible light. In this article, the pathogenesis, clinical features, investigations, and treatment of CAD will be discussed.
