title: [Oral allergy syndrome due to cashew nuts in the patient without pollinosis].
abstract: A 26-year-old woman felt tingling on her tongue and itching both in the throat and on the face immediately after she put a cashew nut on her tongue. She had a history of atopic dermatitis and bronchial asthma, but not of pollinosis. CAP-FEIA and skin prick test (SPT) were positive for cashew nuts. The results showed negative for peanuts and other tree nuts than cashew nuts. Consequently, she was diagnosed with oral allergy syndrome due to cashew nuts. In addition, the result of skin prick test with cashew nuts normalized one year after she began avoiding cashew nuts, indicating that cashew nuts allergy would be due to sensitization by itself rather than to cross-reactivity between cashew nuts and pollens in this case.
