Bier spots in two children.

Bier spots are a distinct pattern of vascular mottling. Most reported cases are in young adults, with the youngest case in the literature at age 15 years. We report two children, ages 11 and 12 years, with Bier spots. Patient 1 was an 11-year-old boy who presented with white spots on the dorsal aspect of his hands. Patient 2 was a 12-year-old girl who presented with similar spots on the dorsal aspect of her left forearm and left hand. In both patients, the spots were visible when extremities were placed in a dependent position and disappeared with elevation of the extremity. Both patients were otherwise healthy.
