Abstract
- Anaphylaxis is an acute serious systemic allergic reaction that can lead to death, requiring immediate diagnosis and treatment. In particular, food is the most common cause in children, adolescents, and young adults. In addition to physical contact between food and skin, anaphylaxis can also be induced by exposure other than ingestion, such as inhalation of aerosolized food proteins. Korean males undergo medical screening prior to a compulsory military service. A history of possible food allergy requires referral to a specialized allergy clinic. A 19-year-old male patient enlisted in the military was referred to the allergy clinic for an oral provocation test. It was confirmed that anaphylaxis was caused not only by walnut intake, but also by skin contact or by inhaling walnut particles. We report the case with the literature review.
