Bier spots
Bier spots are small, light flat spots usually found on the arms and legs of young adults, in which the intervening skin may seem red but blanches with pressure so that these light spots disappear.[1] This is a benign physiologic vascular anomaly of no significance clinically.[2]
Signs and symptoms
-
Pale flat spots
-
Spots more apparent on keeping hands down
-
Spots disappear on raising hand
Diagnosis
The spots appear when the blood is congested with a bandage on the upper arm, e.g. with a blood pressure cuff.
The spots also appear when the arms are slightly raised from the trunk (angle approx. 45°) and disappear again when the arms are stretched upwards.[3]
-
Stratum corneum with characteristic normal basket weave appearance, normal epidermis and basal cell layer.
Treatment
It is a physiological phenomenon that requires no treatment.[3]
