Summary
Atopic dermatitis is a common illness in pediatric age. Children with atopic dermatitis are prone to develop cutaneous sensitization due to skin barrier dysfunction and immune dysregulation. Recent studies have shown a higher prevalence of certain allergens, which identification may be clinically relevant and have implications for atopic dermatitis management. Considering the most prevalent and relevant allergens based on a retrospective analysis of 145 pediatric patients, 44,1% (n = 63) with atopic dermatitis, and comparing the positive results, we propose the application of an adapted baseline series with the most relevant 20 allergens for the Portuguese pediatric population with atopic dermatitis with recommendation for an evaluation of allergic contact dermatitis. 

Key words
Atopic dermatitis; allergic contact dermatitis; prevalent allergens; baseline serie; pediatric patients.
