A Case of Pressure Urticaria Treated with a Leukotriene Inhibitor / 대한피부과학회지

Delayed pressure urticria is a type of physical urticaria, characterized by the appearance of painful swelling for a few hours after physical stimulus. A 27-year-old woman suffered from pressure urticaria for eight months. The patient was unresponsive to conventional antihistamine, glucocorticoid, cyclosporine and azathioprine. Since the patient was treated with 10 mg/day montelukast and 1 mg/day ketotifen for 10 months, erythema and wheals have not developed. We report a case of pressure urticaria treated with a leukotriene inhibitor.
