An urticarial reaction associated with high fever developed in a welder on four occasions while he was welding steel profiles filled with polyurethane. The fumes emitted during pyrolysis of polyurethane and inhaled by the patient probably caused the urticarial reaction. Provocation tests with two pyrolysis products, 4,4-diphenylmethane diisocyanate and 4,4-diaminophenylmethane, were negative. This case demonstrates the difficulty in detecting the cause of urticaria induced by airborne chemicals.
一名焊工在焊接填充聚氨酯的钢型材时，曾四次出现伴有高热的荨麻疹反应。聚氨酯热解过程中释放并被患者吸入的烟雾可能导致了荨麻疹反应。对两种热解产物4,4-二苯基甲烷二异氰酸酯和4,4-二氨基二苯甲烷进行的激发试验结果为阴性。该病例表明，检测由空气中化学物质引起的荨麻疹病因存在困难。
