What is leukonychia?

Inflammation of the nail matrix
Increase and enlarged curvature of the nail
Spots of discoloration on the nail plate
White spots appearing in the nail

The correct answer is: Inflammation of the nail matrix

Leukonychia refers specifically to the presence of white spots or patches on the nail plate. This condition can be caused by a variety of factors, including trauma to the nail matrix, allergic reactions, or underlying health issues. The correct understanding of leukonychia is that it manifests as white discoloration, making it distinct and recognizable. The other options describe different conditions or phenomena related to nails but do not capture the essence of leukonychia. While inflammation of the nail matrix can lead to other complications, it does not specifically define leukonychia. Similarly, increased curvature of the nail pertains to different nail abnormalities, and spots of discoloration could imply various nail conditions but are more general than the specific white spots indicative of leukonychia.
