Cold urticaria (essentially meaning cold hives) is a disorder in which large red welts called hives (urticaria) form on the skin after exposure to a cold stimulus. [1] The hives are usually itchy and often the hands, feet and other parts of the body will become itchy and swollen as well.
Cold urticaria is diagnosed by dabbing an ice cube against the skin of the forearm for 1 to 5 minutes. A distinct hive should develop if a person has cold urticaria. This is different from the normal redness that can be seen in people without cold urticaria.
Cold injury (or cold weather injury) is damage to the body from cold exposure, including hypothermia and several skin injuries. [6] Cold-related skin injuries are categorized into freezing and nonfreezing cold injuries. [5] Freezing cold injuries involve tissue damage when exposed to temperatures below freezing (less than 0 degrees Celsius).
This condition is characterised by cold induced urticaria, autoimmunity, atopy and humoral immune deficiency. [2] The humeral immune deficiency results in recurrent bronchopulmonary infections. Cutaneous granulomas may also occur. [citation needed] The urticaria usually appears within 12 months of birth but may appear immediately after birth. [3]

[14] The term autoimmune urticaria refers to a subset of chronic spontaneous urticaria (CSU) cases where the immune system appears to play a significant role. This understanding began to evolve in the mid to late 20th ...
