title: A man with an infected finger: a case report.
abstract: BACKGROUND
  Whitlow is an infection of a finger or around the fingernails, generally caused by bacterium. However, in rare cases, it may also be caused by the herpes simplex virus. As herpetic whitlow is not seen often, it may go under-recognised or be mistaken for a different kind of infection of the finger. Delayed recognition and/or treatment puts patients at risk of complications ranging from superinfection to herpetic encephalitis.
  
  
  METHODS
  A 23-year-old Caucasian man with no medical history was referred by his primary care physician because of erythema and swelling of the little finger of his left hand. The primary care physician had already treated him with the oral antibiotic Augmentin® (amoxicillin-clavulanic acid) and incision of the finger, but this had not resolved his complaints. He had multiple vesicles on the finger, which led to the diagnosis of herpetic whitlow, which we confirmed by polymerase chain reaction testing. All cutaneous abnormalities disappeared after treatment.
  
  
  CONCLUSIONS
  Whitlow is rarely caused by the herpes simplex virus, but this disease requires a swift recognition and treatment to prevent complications. This case serves to emphasise that not all whitlow is caused by a bacterial infection, and that it is important to differentiate between herpetic and bacterial whitlow, as these diseases require a different treatment.
