Chronic actinic dermatitis.
A 52-year-old man experienced a pruritic and erythematous eruption on his face, neck, upper chest, and arms. On examination his lesions consisted of edematous, erythematous plaques with scale and lichenified plaques. His clinical presentation, a skin biopsy specimen with a spongiotic dermatitis, positive patch and photopatch tests, and low MEDB and MEDA tests provided a diagnosis of chronic actinic dermatitis.
