[Chilblains]. / Engelures.

Chilblain is an erythrocyanotic lesion of hands or feet, occurring after prolonged exposure to moderate to cold humidity. Most common in young and slim women, it can happen at every age, and relapses characteristically in autumn and winter. Clinical diversity is the rule, in frequent association with microvascular dysreactivity (mostly acrocyanosis). Chilblain is benign in most cases.
