Painful inflammation of small blood vessels of the skin is called chilblains. Sudden warming up of body from cold temperature results in chilblains.
A chilblain is also known as pernio. It is characterized by itching, red patches, swelling and blistering on toes, fingers, ears and nose.
Commonly chilblains affect the following parts of body: Fingers and toes, legs, heels and ears.
Due to cold exposure or in humid or damp conditions there is abnormal vascular response. Minor trauma may aggravate the condition.
Chilblains are a common occurrence. The abnormal reaction of skin to cold results in chilblains. Chilblains commonly occur on extremities as it easily becomes cold.
When the skin becomes cold the blood vessels under the skin become narrow resulting in slow supply of blood to that area of skin. On warming up of the skin there is some leakage of fluid from blood vessels into the surrounding tissues. This results in inflammation and hence chilblain develops.
Age / Sex prevalance of chilblains
It is more common among young and middle-aged women and in children.
Chilblains occur as a result of an abnormal reaction of the body to cold. Chilblains develop on the skin that has been exposed to sudden cold and warm temperatures e.g. sudden warming of cold hands directly in front of fire that result in expansion of small blood vessels under the skin causing leakage of blood into nearby tissues.
Chilblains may be a result of various systemic diseases as follows:
• Anorexia nervosa.
• Chronic myelomonocytic leukemia.
• Raynauds disease.
• Cryoglobulinemia, cryofibrinogenemia, cold agglutinins.

• Corticosteroid creams to relieve itching and swelling.
• Blood pressure lowering drugs.
