Bier's spots 1예

Abstract

Bier’s spots are distinct patterns of vascular mottlings composed of small, irregular and pale macules, often triggered by external compression of the limbs. The macules appear as either red or white areas standing out against the cyanotic congestion. It is considered as an exaggerated physiological response of cutaneous small blood vessels to venous hypertension. If the venous stasis is reduced by raising the limbs or taking off the tourniquet, the spots disappear but tend to recur in the same places if elicitation is repeated. We report a case of Bier’s spots on both forearms in a 21-year-old male.
