Bier's spots present as vascular mottling, and this consists of small, irregular macules surrounded by a red to cyanotic background. The macules most commonly occur on the arms and legs of young adults, but they may also appear on the trunk. They are considered a vascular anomaly, with vasoconstriction in the pale areas and vasodilatation in the erythematous skin. Although Bier's spots are occasionally discovered in young adults, they are still a challenge to differentiate from other hypopigmentation disorders. We report here on two cases of Bier's spots on the extremities and trunk of 2 young adults.
