Chronic actinic dermatitis
Synonyms: Actinic reticuloid | Chronic photosensitivity dermatitis
Chronic actinic dermatitis (CAD) is an immunologically mediated photodermatosis usually observed in temperate climates and that typically develops in middle-aged to elderly males. CAD is characterized by eczematous and often lichenified pruritic patches and confluent plaques located predominantly on sun-exposed areas with notable sparing of eyelids skin folds and postauricular skin. It is often accompanied by multiple contact allergies and usually occurs in a background of either atopic contact allergic or seborrheic dermatitis although it can occur de novo. Resolution of photosensitivity is reported in up to 50% of individuals after 15 years or more with contact allergies persisting.
