What are eggshell nails characterized by?

• A. Thick and brittle nail plates
• B. Flexible and thin white nail plates
• C. Curved nail plates with ridges
• D. Splitting and discoloration

Answer: (B)

Eggshell nails are characterized by flexible and thin white nail plates. This condition results in nails that appear fragile and delicate, often lacking the normal strength found in healthy nails. The thinness of eggshell nails makes them susceptible to bending and breaking easily. Additionally, the whitish appearance of the nails is a key identifying feature, distinguishing eggshell nails from other types of nail disorders.

When considering other characteristics, such as thick and brittle nail plates or splitting and discoloration, they pertain to different nail conditions that do not align with the definition of eggshell nails. Curved nail plates with ridges also indicate other nail issues, but they are not relevant to the definition of eggshell nails. Understanding these specific characteristics helps in proper diagnosis and treatment planning in nail care.
