Acrocyanosis
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 of the fingers and wrists and the toes and ankles and by profuse sweating and coldness of the fingers and toes. Acrocyanosis is caused by narrowing (constriction) of small arterioles (tiny arteries) toward the end of the arms and legs.
