Therapeutic Approach

Chronic actinic dermatitis (CAD) is an uncommon, but important, form of eczematous dermatitis that involves severe abnormal cutaneous photosensitivity (nearly always to ultraviolet B, usually to ultraviolet A and often also to visible light). It typically arises on top of another preexisting dermatitis (such as atopic eczema, seborrheic dermatitis, or contact allergic dermatitis). Often, even when not arising from it, contact allergy is another contributing component. The mainstay of management is avoidance of the relevant wavelengths of ultraviolet and visible light. While behavioral, environmental, and clothing photoprotection are of high importance, topical sunscreens are also part of photoprotection. Avoidance of identified contact allergens is also important. Below are specific treatments for CAD. Systemic immunosuppressive approaches are appropriate if avoidance measures and topical treatments are insufficient. Always before any phototherapy or PUVA treatments, these patients should be assessed in an expert photodermatology unit. See Table 93-1.
