Bathing is one of the factors involved in the development of food-dependent exercise-induced anaphylaxis (FDEIA). Here, we report a case of FDEIA induced by bathing after peach ingestion in an 8-year-old girl. The patient had taken a bath 10 minutes after eating a raw peach. Thirty minutes later, she experienced anaphylaxis. She underwent prick-to-prick testing for peaches, and the results were positive. Her peach-specific IgE levels were 5.35 UA/mL. Peach-induced anaphylaxis was suspected, and an oral food challenge test for raw peaches was conducted; however, the findings were negative. Later, anaphylaxis was induced by an exercise challenge test, performed after the patient received aspirin and ingested a raw peach. Based on the above findings, she was diagnosed with FDEIA induced by a peach. Upon performing allergen component analysis, Prup 3 was negative and Prup 7 was positive. The mechanism by which bathing induces FDEIA is not well understood. There have been few reports of FDEIA induced by bathing after meals. Our case shows that bathing should be recognized as a factor involved in FDEIA onset.
