Nail fold
The crescent-shaped skin fold that covers the edges of the nail plate of the fingernail or toenail - with the exception of the free (distal) edge - is referred to as the nail fold (syn. Nail fold or nail wall, technically perionychium, paronychium ) .
This fold of skin protects the new nail plate before it becomes visible and is not yet completely firm. It is called the proximal nail fold (closer to the body, i.e. the part that covers the crescent-shaped lunula). The skin on each side of the nail plate is an extension of the proximal nail fold; it is also called the lateral nail fold. The gap between the nail plate and the nail fold is sealed by the cuticle ( eponychium ).
Diseases
An ingrowth of the nail plate into the nail fold leads to a unguis incarnatus . Paronychial warts can form at the nail fold and develop into candida onychomycosis . Diseased chewing of the nail fold is called perionychophagia .
