Foot dermatitis in children: causative allergens and follow-up.

Allergic contact dermatitis from shoes may have a typical pattern of presentation, but we have found that the distribution of dermatitis is often unhelpful in establishing the diagnosis. In this study, we aimed to define the features of foot dermatitis in children and to assess its outcome, in comparison to adults with foot eruptions. Relevant allergens were found in 15 out of 29 children and 26 out of 57 adults with foot eruptions. The most common allergens in children were rubber chemicals and topical medicaments. Adults showed a similar pattern, but also reacted to clothing dyes. The prognosis in both groups was good, with the dermatitis improving or resolving in 2/3.
