A cutaneous abscess could occur at multiple locations.

Patients who require hospitalization for ICU admission, operating room surgical intervention, or death have one of the following six risk factors upon presentation[4]:

  • abnormal cross-sectional imaging result
  • systemic inflammatory response syndrome
  • previous infection at the same location
  • infection involving the hand
  • diabetes
  • age >65 years
