Beau's Lines Statistics

  • Mee’s lines are transverse white bands that frequently affect multiple nails, and are classically associated with arsenic poisoning.
  • Children and active adults commonly have one or more white lines or spots on one or more nails, a condition known as leukonychia.
  • Changes in the color of the moon (lunula) can be revealing—heart failure can turn it red, while tetracycline therapy can make it yellow.
