A cosmetologist is performing a manicure and notices that the client's nails have visible depressions running across the width of the nail plate. This condition is most likely:

  1. APterygium
  2. BBeau's lines
  3. CLeuconychia
  4. DOnychophagy
Show answer & explanation

Correct answer: B. Beau's lines

Beau's lines are visible depressions running across the width of the natural nail plate. They are usually a result of a major illness, injury, or trauma that temporarily impairs nail matrix function.

Why the other options are wrong

  • A. Pterygium is the forward growth of the eponychium or hyponychium over the nail plate.
  • C. Leuconychia refers to white spots or discoloration on the nail.
  • D. Onychophagy is the term for nail biting, not a physical depression.

Beau's Lines

Transverse depressions on the nail plate, indicating a temporary halt or slowing of nail growth.

  • Visible horizontal lines/grooves
  • Caused by illness, injury, or stress
  • Grow out with the nail

Memory trick: Beau's lines across, tell of a past growth loss.
