Which term refers to the overgrown cuticle that becomes attached to the nail plate?

Onycholysis
Onychorrhexis
Paronychia
Pterygium

The correct answer is: Pterygium

Pterygium refers to the overgrown cuticle that becomes attached to the nail plate, causing it to appear elongated and thickened. Onycholysis (A) is the separation of the nail plate from the nail bed, typically caused by trauma or a fungal infection. Onychorrhexis (B) is the splitting or brittleness of the nail caused by repeated exposure to harsh chemicals or injury. Paronychia (C) is a bacterial or fungal infection of the nail fold, which is the skin around the nail. None of these terms accurately describe the overgrowth of the cuticle onto the nail plate.
