The syndromes of idiopathic anaphylaxis, exercise-induced anaphylaxis, and other physical allergies are well described as separate entities. This article describes the combination of these problems in the same patient. Two patients with idiopathic anaphylaxis are described. One also has exercise-induced anaphylaxis, and one also has exercise-induced bronchospasm and exercise-induced urticaria and angioedema. A third patient with exercise-induced anaphylaxis, idiopathic urticaria, angioedema, cholinergic urticaria, and dermatographism is described.
