White Avascular Spots or Bier Spots

White avascular spots, AKA Bier spots, are white spots on the skin are caused by a relative lack of blood. They are entirely benign.


White avascular macules approximately 5 mm. in size may occasionally be seen on the arms and legs of patients, especially white women. Rarely they are numerous enough to prompt a patient to seek medical attention. The white macules are due to decreased blood content probably secondary to local arteriolar vasoconstriction.


No treatment is needed nor known effective.
