We report a case of crown daisy-dependent exerciseinduced anaphylaxis in a patient with mugwort-sensitized pollinosis, which is the first case as far as we know. A 41-year-old female with rhinitis experienced the generalized urticaria, angioedema and syncope on walking about 1 hour after ingestion of grilled pork and boiled rice wrapped with crown daisy, lettuce and sesami leaf during mountain climbing. Skin prick tests for food allergens showed the strong positive reaction to crown daisy, and those for inhalant allergens showed strong positive reactions to mugwort and other weed pollens. Her PC20-methacholine was 5.6 mg/mL. Exercise challenge and an oral challenge with crown daisy showed negative results. However, exercise challenge 1 hour after ingestion of crown daisy revealed a positive reaction manifested with generalized urticaria, angioedema and hypotension. She was diagnosed with crown daisy-dependent exercise-induced anaphylaxis.
