What term refers to a cuticle that splits around the nail?

The term that refers to a cuticle that splits around the nail is pterygium. Pterygium occurs when there is an abnormal growth of skin at the nail fold, often causing the cuticle to separate from the nail plate, resulting in a split or irregular appearance. This can lead to discomfort and can impact nail health if not properly managed.

Leukonchia relates to white spots or streaks on the nails, which is not connected to the splitting of the cuticle. Tinea pedis is a fungal infection commonly known as athlete's foot, which affects the skin on the feet, not the nails or cuticles. Onychorcryptosis, also known as an ingrown nail, refers specifically to a condition where the nail grows into the surrounding skin, which is distinct from issues related to the cuticle. Understanding these terms helps clarify the specific conditions they describe, isolating pterygium as the correct answer in the context of cuticle issues.
