Chronic urticaria is a common condition characterised by intense pruritus, wheals and erythema. A 56-year-old female presented with chronic urticaria which persisted despite multiple therapies. Laboratory and radiological investigations were performed and a mucinous breast cancer detected. Within days of surgical resection of the breast cancer, the urticaria resolved. This paper outlines the major causes of chronic urticaria and the importance of investigating patients with chronic urticaria.
