Abstract
- Chronic actinic dermatitis is an uncommon, persistent, light induced eruption occurring mostly on exposed skin. It is eczematous or pseudolymphomatous in nature, probably representing delayed type hypersensitivity to endogerious photoallergens. It usually worsens in summer and affects elderly men. A 72-old-male was presented with a 14 month history of pruritic skin lesions. They were composed of waxy thickened scaly plaques of the face and dorsa of the hands, and depigmented patches of the neck, which worsened when exposed to sun light. We performed photo test and photopatch test. MED of UVA was lowered and the patch and photopatch test revealed only contact sensitivity to Balsam of Peru, perfume mix and fragrance mix. A biopsy specimen showed hyperkeratosis and spongiosis of the epidermis and perivascular lymphocytic and many eosinophilic infiltrations of the dermis. The patient was treated with systemic and topical corticosteroids with marked improvement.
