Abstract

BackgroundEgg allergy is one of the most frequent food allergies in childhood while adult onset of egg allergy is a rare condition.Case presentationWe 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.ConclusionsEven though IgE-mediated egg allergy affects children, this report witnesses a rare case of adult onset.

Highlights

Egg allergy prevails in pediatric population, some studies have described the persistence or newly onset egg sensitization through adults [1]

Summary

Introduction

Egg allergy prevails in pediatric population, some studies have described the persistence or newly onset egg sensitization through adults [1]. Intestinal inflammatory disorders, such as Crohn disease, celiac disease, or ulcerative colitis favor the development of food allergy by altering intestinal permeability It has been reported a case of late-onset egg allergy following the diagnosis of Hodgkin’s lymphoma and start of chemotherapy and the authors speculated an alteration involving bowel mucous membrane [8]. No familial history for atopy is present In childhood, he did not suffer from atopic dermatitis nor egg or other food allergies while a history of contact dermatitis related to nickel and mild allergic rhinoconjunctivitis to grass pollen is reported. He did not suffer from atopic dermatitis nor egg or other food allergies while a history of contact dermatitis related to nickel and mild allergic rhinoconjunctivitis to grass pollen is reported He is not affected by immunodeficiency or chronic inflammatory bowel disease, nor disorders affecting the biliary tract or intolerance to lactose.
