Periorbital dermatitis has an incidence of 3.9-4.8%. It is most commonly caused by contact allergy (54%) (direct contact 44% or airborne contact 10.2%), irritant contact dermatitis (9.1%) and atopic dermatitis (25%). Metals are reported among the main causes of airborne allergic contact dermatitis in particular in occupational settings. We report an unusual case of periorbital airborne allergic contact dermatitis together with direct allergic contact dermatitis of the hands in a teacher. It was found to be due to metals in the powder of blackboard chalk.

Abstract
Periorbital dermatitis has an incidence of 3.9-4.8%. It is most commonly caused by contact allergy (54%) (direct contact 44% or airborne contact 10.2%), irritant contact dermatitis (9.1%) and atopic dermatitis (25%). Metals are reported among the main causes of airborne allergic contact dermatitis in particular in occupational settings. We report an unusual case of periorbital airborne allergic contact dermatitis together with direct allergic contact dermatitis of the hands in a teacher. It was found to be due to metals in the powder of blackboard chalk.File in questo prodotto:
