A 17-year-old boy presented with dyspnea and urticaria after eating okonomiyaki prepared at home with an okonomiyaki mix. Many mites were detected in the okonomiyaki mix, which was past its sell-buy date. We performed skin prick tests for several allergens, and obtained positive results for the okonomiyaki mix, house dust extract, and mite extract, among others. We diagnosed oral mite anaphylaxis (OMA) caused by the okonomiyaki mix. The mites were identified as Dermatophagoides siboney (D. siboney). D. siboney was also detected in house dust from the patient's home. This is the first time that D. siboney has been detected in Japan. Furthermore, this is the first case of OMA caused by D. siboney to be reported worldwide.
