Acrocyanosis

What Is Acrocyanosis?

Acrocyanosis is blueness of the extremities (the hands and feet). Acrocyanosis is typically symmetrical. It is marked by a mottled blue or red discoloration of the skin on the fingers and wrists and the toes and ankles. Profuse sweating and coldness of the fingers and toes may also occur.

Acrocyanosis is caused by narrowing (constriction) of small arterioles (tiny arteries) toward the end of the arms and legs.
