Abstract

<p>The patient was a 6-year-old girl who had two episodes of frequent vomiting approximately 3 hours after eating school lunch. On both occasions, the only symptoms were vomiting and fatigue, which improved the next day. Cashew nuts were common to the items consumed. She had never eaten cashew nuts before the first episode. The patient was receiving treatment for bronchial asthma. Her brother also had a food allergy, while her parents had hay fever. Prick test of cashew nuts and cashew nuts-specific IgE test yielded negative results. Also, an oral food challenge test with cashew nuts induced vomiting 2 hours after ingestion. She was diagnosed with food protein-induced enterocolitis syndrome (FPIES) caused by cashew nuts. In recent years, the consumption of cashew nuts has been increasing, and this has been accompanied by an increase in IgE-related allergies. However, reports of FPIES by cashew nuts are rare. Since cashew nuts are occasionally served in school lunches, they may induce an allergy in school-age children.</p>
