Answer

Physical findings in acute paronychia include the following:

  • The affected area often appears erythematous and swollen

  • In more advanced cases, pus may collect under the skin of the lateral fold

  • If untreated, the infection can extend into the eponychium, in which case it is called eponychia

  • Further extension of the infection can lead to the involvement of both lateral folds as it tracks under the nail sulcus; this progression is called a runaround infection
