Chronic actinic dermatitis is a rare disease worldwide and also in Korea. However there has been no clinicohistologic and photobiological analysis of chronic actinic dermatitis in Korea. We examined 11 patients who were diagnosed as chronic actinic dermatitis and the results of this study were compared with previous reports. Most patients were elderly men who had erythematous papules or lichenified plaques on sun-exposed areas such as the face, neck, and dorsum of the hands with severe itching sensation. All patients had severe sensitivity to UVB and biopsied specimens showed findings of chronic eczema. Five patients had positive photopatch test materials. The patients were treated with systemic and topical steroid, cyclosporine and antihistamine.
