Summary: | Cold-induced urticaria is considered as a subtype of physical urticaria and also the second most common type of chronic inducible urticaria. Contact with cold surfaces or the environment may cause systemic reactions, especially during aquatic activities. A 22-year-old female patient with a history of sulfa drug allergy began her condition 2 years before the presence of generalized pruritic erythema with hives as well as 2 episodes that had been characterized by facial angioedema and syncope 3-5 minutes after being in contact with cold air or surfaces. On both events, she had just been outdoors on a cold, winter day. She was suspected to have cold-induced urticaria; thereby she had a positive reaction to the ice cube test. Due to the previous episodes of anaphylaxis, the patient was trained to administer intramuscular epinephrine. After 4 weeks of starting the treatment with antihistamines, no new events or injuries had occurred. Cold-induced urticaria may cause life-threatening reactions. The rate of anaphylaxis in these patients is low however, this case is presented to inform the importance of identifying this type of systemic reaction and preventing strategies.
