The white spots in the nail caused by an injury with a small separation between the nail and nail bed are called:

• A. Leuconychia
• B. Beau's lines
• C. Melanonychia
• D. Onycholysis

Answer: (A)

White spots on the nail after a minor injury are leuconychia. They occur when the nail plate has small disruptions or tiny air spaces from trauma, which reflect light differently and look white. This is distinct from a true separation of the nail from the nail bed, which is onycholysis and presents as lifting of the nail rather than white spots. Beau's lines are horizontal ridges caused by systemic stress, melanonychia is dark pigmentation of the nail, and onycholysis describes actual detachment of the nail plate from the nail bed.
