The spontaneous resolution of photosensitivity and contact allergy in a patient with chronic actinic dermatitis.

Chronic actinic dermatitis (CAD) is an uncommon photodermatosis in which patients typically exhibit photosensitivity together with contact allergy. Improvement of the photosensitivity over time is well recognized in a proportion of patients but the concurrent resolution of contact allergy is rare. We report on a 46-year-old female with longstanding CAD who demonstrated resolution of both of these features.
