A 10-year-old boy developed acute respiratory distress after the ingestion of a cake prepared with mite-contaminated wheat flour. Although there was no previous history of asthma, the patient was admitted to hospital with the diagnosis of an asthma attack. Only after examination of the flour, the identification and quantification of mites and the allergological evaluation of the patient a diagnosis of oral mite anaphylaxis (OMA) was concluded. This case highlights the fact that OMA can be misdiagnosed as asthma if the physician does not entertain other diagnostic possibilities when evaluating a patient with an acute respiratory ailment in the emergency room. Moreover, it raises questions on the induction of acute bronchospasm from the exposure to mite allergens through the oral route.
