Abstract

Abstract:  A teenager with atopic dermatitis presented with a 12-month history of recurrent, pruritic, round and polygonal patches on her face. Patch tests using the European standard series (including nickel, chromium, and cobalt chloride), a plastic and glue series of allergens, polyester components, and personal and environmental products in contact with the patient were conducted. For the patient and 3 of 14 healthy volunteers, positive reactions were observed to the patient’s mobile phone touchscreen (TS), an extract solution from the TS, and a non-TS phone of another brand. Accordingly, the patient’s dermatitis disappeared when contact with mobile phone screens was avoided.
