An adult-onset egg allergy

The development of egg allergy in the late adulthood is rare. In most of the cases, symptoms begin in childhood or early adulthood. Adult-onset egg allergy usually develops either as an occupational disease inflicting workers in bakery and confectionery industries or a bird-egg syndrome caused by cross-reactivity in patients suffering from bird feather sensitivity. Herein we present an adult-onset primary egg allergy appeared differently from the previously reported cases based on the absence of occupational exposure and bird as well as aeroallergen sensitization.
