Allergic Contact Dermatitis Evaluation: Strategies for the Preschooler

Purpose of Review: The environment for the developing children is complex as they are exposed to a variety of activities and settings where potential environmental allergens may be encountered. Recent evidence supports the clinical benefit of patch testing young children suffering from recalcitrant dermatitis. While patch testing has been recently approved by the Food and Drug Administration in children ages 6–18 years old, patch testing strategies for young children of preschool age (between 2 and 6 years old) have yet to be defined. Recent Findings: Allergic contact dermatitis is underdiagnosed among pediatric patients, particularly those suffering from concomitant atopic dermatitis as the interplay between the two diseases is complex. Recent reports in literature supported the clinical value, safety, and efficacy of patch testing pediatric patients. Summary: This review provides an overview of specific pediatric allergens, special considerations, practical modifications, and systematic exposure-driven guidance approaches toward patch testing preschoolers.
