A Case of Cow's Milk Allergy with Atopic Dermatitis

Nowadays the use of cow's milk as a substitute for human breast milk is gradually increasing and many adverse reactions have been reported. Cow's milk is one of the important allergens, causing skin symptoms in infancy. We experienced a case of atopic dermatitis in a 9-month-old male infant having allergy to cow's milk. He showed itch, erythema and edema on the perioral area within a few minutes after oral feeding of cow's milk. During oral provocation, the infant showed clinical symptoms in concordance with intake of cow's milk. Diagnosis of cow's milk allergy was confirmed by skin prick test and open oral food challenge test with cow's milk. The patient has been treated successfully with the elimination of cow's milk. We report the case with a brief review of related literatures.
