What term refers to the infection of the skin around a nail?

The term that refers to the infection of the skin around a nail is paronychia. This condition typically occurs when bacteria or fungi invade the skin around the nail, often leading to swelling, redness, pain, and pus formation. Paronychia can happen due to various factors, including trauma to the area, biting of the nails, or prolonged exposure to moisture.

Onychomycosis refers specifically to a fungal infection of the nail itself, rather than the surrounding skin. Dermatitis encompasses a broad range of skin irritations and conditions, which may include inflammation but does not specifically denote an infection around a nail. Cellulitis is a deeper skin infection that affects the dermis and subcutaneous tissues but is more widespread and not localized specifically around the nail area. Thus, paronychia is the appropriate term for an infection surrounding the nail.
