Airborne contact dermatitis involved aerosolized particles
Airborne contact dermatitis is a unique type of contact dermatitis originating from volatile substances in an aerosolized, or airborne fumes without direct handling. Some of volatile particles originate in heating and more likely disseminate in particles into atmosphere. When released into the air, the volatile particles settle on the exposed skin, producing a delayed type hypersensitivity reaction or an irritant contact reaction. The latter is estimated to be underreported and is believed to be more frequent than allergic airborne contact dermatitis. In addition, the causative agent may induce phototoxic or photoallergic airborne contact dermatitis or airborne contact urticaria. Volatile particles come into contact with uncovered and also covered areas of the skin. Some harmful agents may involve classic allergic contact dermatitis with direct handling producing typical evolutive polymorphism in clinical appearance. However, aerosolized particles evoke airborne contact dermatitis producing different clinical appearance. These substances include cement, nickel, sesquiterpen lakton (plant allergen), etc. In Europe, prevalence of airborne contact dermatitis increases in occupation environment.
