Paronychia

Paronychia is an inflammatory or infectious disorder of the perionychium, involving the lateral and proximal nail folds of the fingers or toes Pathophysiologically, it typically develops when a disruption of the epidermal barrier between the nail plate and the surrounding cuticle permits the infiltration of pathogens, irritants, or allergens The condition is broadly classified as acute, predominantly driven by bacterial invasion—most commonly *Staphylococcus aureus*—or chronic, frequently manife...

Clinically, paronychia is characterized by localized erythema, edema, warmth, and throbbing pain surrounding the nail fold, with the potential for abscess formation, nail plate dystrophy, and cuticle separation
