Cold-Induced Urticaria in a Paediatric Patient: A Case Report and Literature Review.

Acquired cold-induced urticaria is a rare form of physical urticaria, especially in children. The variety of clinical presentations and the low estimated prevalence contribute to its underdiagnosis. Given the associated risk of anaphylaxis, it is crucial to alert clinicians to the different forms of presentation, diagnosis, and treatment. Starting with a case report of acquired cold-induced urticaria in a previously healthy nine-year-old boy, the authors then review the literature about acquired cold-induced urticaria and discuss the diagnostic exams and disease management.
