What is the name for the condition where the nails appear white and opaque?

• A. Leukonychia
• B. Achromia
• C. Onycholysis
• D. Clubbing

Answer: (A)

Leukonychia is the term used to describe a condition characterized by the nails appearing white and opaque. This condition can occur for various reasons, including trauma to the nail matrix, systemic health issues, or as a genetic trait. The white discoloration can be partial or total and may be indicative of underlying health conditions such as kidney disease or other systemic disorders.

In contrast, other conditions mentioned do not refer to white and opaque nails. Achromia pertains to the absence of pigment, typically affecting the skin or hair rather than the nails. Onycholysis describes a condition where the nail separates from the nail bed, which can change the appearance of the nail but does not specifically involve the opaque white look associated with leukonychia. Clubbing involves a significant alteration in nail shape, presenting wider and curved nail deformities often related to respiratory or cardiovascular issues, diverging significantly from the appearance profile of leukonychia.
