Immediate-pressure urticaria--a distinct disorder.
We report a patient who has an immediate wealing response to pressure in the absence of symptomatic dermographism, which we designate 'immediate-pressure urticaria'. Our patient also suffered from cholinergic urticaria and chronic idiopathic urticaria in the past, demonstrating the clustering of urticarias which frequently occurs.
