ICD-11 NF03.0 — Chilblains
Chilblains are the result of cold-induced damage principally to the microvasculature of acral skin in susceptible individuals. They are commonest in the winter months in cold, damp climates. They present as itchy or painful red-purple macules, papules or plaques, most commonly affecting the fingers and toes, though other body extremities including the heels, nose and ears can be involved. Because of insulation from core body temperature, other areas, especially the lateral thighs, may be involved in areas where there is a thick layer of subcutaneous fat.
