Mild form of cold injury characterised by recurrent, localised painful erythema related to exposure to cold.
Aetiology:
4 stages:
1)
• initial stage – often goes unnoticed
• due to vasoconstriction

3) Congestive/cyanotic stage
• swollen and cyanotic
• may resolve or ulcerate
4) Ulcerative stage
• ‘broken’ chilblain, especially if site of chilblain is ‘traumatised’
Chilblains appear to be part of cryoglobulinaemia and some forms of systemic lupus erythematosus
