Abstract

Nickel is the most common cutaneous contact allergen in children. Allergic contact dermatitis eruption is typically localized to the skin areas that come into contact with the allergen and usually presents as recurrent eczematous lesions on the sites of direct contact. We report an adolescent patient who had severe edema of the face mimicking angioedema after the application of boiled chickpea water and has been found to have allergic sensitization to nickel and cobalt. We want to emphasize the unusual presentation of allergic contact dermatitis and different sources of nickel exposure contrary to those already known. This article is protected by copyright.
