What is it?

Acrocyanosis is a peripheral vascular disorder, characterized by discoloration of the hand, feet, and sometimes the face. The condition is caused due to constriction of small vessels of the skin due to cold weather.

Signs & symptoms

Primary acrocyanosis symptoms are bilateral, symmetrical, painless and persistent blue discoloration of the fingers and toes. Other symptoms may also include hyperhidrosis of the hand and feet, cold hands and feet and swelling of digits. Secondary acrocyanosis symptoms depend on the underlying cause but the discoloration may be asymmetrical and painful.


Diagnosis is based upon findings from medical history and physical examination. Further evaluation may include blood and urine tests, chest x-ray, skin biopsy and nailfold capillaroscopy.


Typically, treatment is not required. It is suggested to avoid exposure to cold or trauma. If acrocyanosis is secondary, treating the underlying cause is necessary.
