Anaphylaxis to the Citrus Fruit Yuzu

Introduction: We report a selective anaphylaxis to yuzu (Citrus junos). Case Presentation: A 42-year-old woman, with no atopic history, has experienced two anaphylactic reactions after consuming yuzu. Skin prick tests (SPTs) were performed with juice, peel and pulp of commercially available lemon, orange, grapefruit, tangerine and yuzu, 2 cultivars of Citrus junos, 2 cultivars of Citrus reticulata, one Citrus ichangensis and food consumed during the culprit meal.
