title: A non-traumatic, blue-purple auricle: case report.
abstract: OBJECTIVE
  We report a typical case of earlobe lymphocytoma.
  
  
  METHODS
  A case report and literature review are presented.
  
  
  RESULTS
  A 10-year-old girl presented with a blue-coloured earlobe. A diagnosis of Lyme disease was confirmed by serological tests. Lyme borreliosis is the most common tick-borne disease in the northern hemisphere. It is caused by the spirochete Borrelia burgdorferi sensu lato. The patient was successfully treated with antibiotics.
  
  
  CONCLUSIONS
  The diagnostic process and ENT symptomatology of Lyme disease and borrelial lymphocytoma are summarised and discussed.
