Cold contact urticaria accounts for approximately 3% of all cases of chronic urticaria. Among all physical urticarias, CCU represents the second most common subtype after symptomatic dermographism. CCU is characterized by the development of wheal and/or angioedema within minutes after cold contact. Extensive cold contact of large areas of skin may lead to systemic reactions such as generalized urticaria, dyspnoea, tachycardia, hypotension and loss of consciousness. Severe CCU has a significant impact on the patient’s quality of life both in a physical and psychological sense.
