Bier spots are an under-recognized cutaneous manifestation of lower extremity lymphedema: a case series and brief review of the literature.

Bier spots represent a benign vascular mottling characterized by multiple irregular white macules along the extensor surfaces of the arms and legs. They have been reported in a variety of diverse conditions with no consistent disease association. We have identified a novel association between these physiologic anemic macules and lower extremity lymphedema. Eleven patients between 23 and 70 years of age (5 male and 6 female) were diagnosed with Bier spots as evidenced by reversible white macules ranging from 3 to 8 mm in diameter on the extensor portions of the feet, ankles, and calves. The thighs were affected as well in 2 morbidly obese subjects. We suspect that these lesions are not uncommon in lymphedema but are simply under-recognized.
