Adult onset egg allergy: a case report

Abstract

Abstract Background Egg allergy is one of the most frequent food allergies in childhood while adult onset of egg allergy is a rare condition. Case presentation We report the case of a 30 years old man sent to our center in order to investigate gastrointestinal symptoms occurring since 2 years after egg and derivatives intake. He did not suffer from egg or other food allergies in childhood. He is an active smoker with a contact dermatitis related to nickel and mild allergic rhinoconjunctivitis to grass pollen. Skin prick test and serum specific IgE to egg were performed and revealed sensitization to egg proteins. Conclusions Even though IgE-mediated egg allergy affects children, this report witnesses a rare case of adult onset.
