Food allergy to egg with the onset at adult age

Allergy to hen's egg is common in infancy. Adult-onset of egg allergy has rarely been mentioned in the literature. In this case report, we demonstrate the 59-year-old woman with the onset of severe atopic eczema at 53 years due to food allergy to egg and other foods with the suspicion of having the bird-egg syndrome. The patient has been found to be sensitized to a lot of aeroallergens including feather or animal dander with clinical symptoms of asthma bronchiale. In the open exposure test the food allergy to egg was confirmed and the severity of atopic eczema was checked out every 2 months after the elimination of egg and other foods. During last 3 years, the patient is without eczematic lesions or suffers from mild form of atopic eczema with dry skin. She eliminates rigorously egg, celery, sea fish and treenuts. During the breaking of the diet regimen, she can now observe not only cutaneous, but also respiratory and gastrointestinal symptoms. (C) 2010 Elsevier Masson SAS. All rights reserved.
