What is characterized by the presence of white spots in fingernails?

1. Onychomycosis

2. Leukonichia

3. Onycholysis

4. Paronychia

The correct answer is: Leukonichia

Leukonichia is characterized by the appearance of white spots or discolorations on the nails, which can occur due to various factors such as minor trauma to the nail bed, allergic reactions, or a systemic issue. These white spots, often referred to as "leukonychia," are usually harmless and may gradually grow out as the nail grows. Onychomycosis, on the other hand, is a fungal infection that typically causes thickening, discoloration, and brittleness in the nails, but it does not specifically present as white spots. Onycholysis refers to the separation of the nail from the nail bed, which usually results in a more dramatic change in appearance, such as lifting or detachment of the nail. Paronychia is an infection around the nail that can cause swelling, redness, and pus formation but does not specifically relate to the presence of white spots on the nail itself. Leukonichia is a common condition that emphasizes the importance of understanding nail health and recognizing the various characteristics of nail disorders.
