What is the term for thickening of the nail plate or abnormal nail growth?

The term for thickening of the nail plate or abnormal nail growth is known as onychomycosis. However, in this instance, the correct answer relates specifically to a certain condition impacting the nail.

Leuconychia refers to white spots or discoloration on the nails and is not directly related to thickening or abnormal growth. Onychomadesis involves intermittent separation of the nail from the nail bed, which does not describe thickening but rather a shedding condition. Onychorrhexis indicates longitudinal ridges or brittle nails, often resulting in split ends, instead of an overall thickening of the nail plate. Onychocryptosis, commonly known as an ingrown toenail, specifically refers to the nail growing into the surrounding skin rather than changing the thickness of the nail itself.

The correct term that pertains explicitly to thickening or abnormal growth is not among the provided choices; however, a choice that reflects some aspect of nail structure, such as leuconychia for discoloration, diverges from the focus on thickness or abnormal growth. It's essential to note the specific definitions and characteristics of these terms to clarify their meanings accurately in the context of nail technology and pathology.
