Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Paronychia is the most common hand infection and is characterized by inflammation and pus accumulation along a lateral nail fold. It may spread to involve the eponychium at the base of the nail and the opposite nail fold if untreated. S aureus is most frequently isolated, although the infection is generally mixed flora. Felon, dactylitis, herpetic whitlow, hydrofluoric acid burn, and traumatic injury should be considered in the differential.
