Introduction: Cold-induced urticaria, rare in paediatrics, is characterised by the development of urticarial lesions and/ or angioedema after cold exposure. Most cases are idiopathic; secondary causes include crioglobulinemia, complement deficits, vasculitis, neoplasins and infections. Commonly it is benign and self-limited, although systemic, potentially fatal neoplasins reactions may occur. Case Report: The authors present a case report of a 16 year-old boy with severe cold induced urticaria. At the age of 14 years he started reproducible episodes of urticaria during aquatic activities, that progressively worsen, and episodes of urticaria and malaise in exposure to cold environment. Two months after he had a sudden onset of generalized urticaria, facial angioedema and syncope after submersion on sea water. It was considered the diagnosis of acquired cold urticaria, type III. Avoidance of cold exposure was recommended; prophylactic treatment was begun with cetirizine and a self-administering epinephrine device was prescribed.

Keywords : anaphylaxis; cold urticaria; epinephrine; ice cube test.
