Cold Urticaria synonyms

Cold Urticaria is most commonly referred to by its primary clinical name, though it is occasionally documented as "cold-induced urticaria" or "cold hypersensitivity." Because it is a distinct form of physical urticaria, medical professionals prioritize the term Cold Urticaria to ensure consistent diagnosis, coding, and communication across global healthcare systems.

What are the common names and synonyms for Cold Urticaria?

While Cold Urticaria is the standard term used in clinical practice and international research, patients may encounter several synonyms in medical literature, older textbooks, or international databases. The most frequent synonyms include "cold-induced urticaria" and "cold-contact urticaria." Historically, some literature may have referred to it as "cold-hypersensitivity," though this term is now considered imprecise as it does not specify the dermatological manifestation of hives. In rare instances, particularly in older European medical texts, you might see it categorized under the broader umbrella of "physical urticaria," which includes other triggers like pressure or vibration.

How is Cold Urticaria classified in medical systems?

Medical nomenclature is strictly regulated to ensure that 650 members of the DiseaseMaps community and others worldwide can accurately share their health data. Standardized classification systems use specific codes to track Cold Urticaria:

• ICD-10 (International Classification of Diseases): Classified under code L50.2, defined as "urticaria due to cold and heat."


• Orphanet: Recognized as a rare skin disease with the unique identifier ORPHA:79410.


• OMIM (Online Mendelian Inheritance in Man): While Cold Urticaria is often acquired, familial forms are documented under specific genetic entries, such as #120100 for Familial Cold Autoinflammatory Syndrome (FCAS), which is a distinct, though sometimes confused, condition.

Why does Cold Urticaria have multiple names?

The existence of multiple names for Cold Urticaria stems from the evolution of clinical dermatology. Historically, physicians named skin conditions based purely on the observed trigger (e.g., "cold-induced"). As our understanding of the mast cell degranulation process improved, the medical community moved toward the term Cold Urticaria to better align with other "urticaria" classifications, such as chronic spontaneous urticaria or solar urticaria. Different countries may occasionally use variations based on linguistic translation, but the medical community globally has converged on Cold Urticaria to avoid confusion with systemic autoinflammatory syndromes that also present with cold-triggered symptoms.

Which term should I use when speaking to my doctor?

When communicating with your healthcare provider, it is best to use the term Cold Urticaria. This is the official terminology recognized by the World Allergy Organization and the European Academy of Allergy and Clinical Immunology. Using this specific term helps your doctor quickly identify the condition in diagnostic databases and ensures that your medical records are accurately coded for insurance and specialist referral purposes. If you have been diagnosed with a familial variant, ensure you clarify this with your geneticist, as the management of hereditary forms differs significantly from the more common acquired form of the disease.

Next steps

• Consult an allergist or immunologist to confirm your diagnosis through a formal ice-cube provocation test.


• Maintain a symptom diary to track triggers and share this data with your clinical team.


• Join the 650 members of our Cold Urticaria community on DiseaseMaps.org to share experiences and coping strategies.


• Request a referral to a genetic counselor if you have a strong family history of cold-triggered symptoms to rule out autoinflammatory conditions.
