Allergic contact dermatitis in children: a practical approach to management.

Allergic contact dermatitis (ACD) may account for at least 20% of all childhood dermatitis. Clinically, its morphology is identical to other forms of dermatitis in acute, subacute and chronic forms. A persistent or unusual and localized pattern is often the key to diagnosis. Treatment has centered around the use of corticosteroids, with the adjunct of antihistamines, wet dressings, and emollients for alleviation of symptoms. The newer topical immunosuppressives, tacrolimus and pimecrolimus, may also hold promise as alternative therapies, although they have not been well-studied in this regard. Allergen identification, sometimes through patch testing and allergen avoidance are the keys to preventing recurrences of this disease.
