title: [Cervical lymphadenitis in an immunocompetent patient: Mycobacterium gordonae as the cause?].
abstract: METHODS
  A 76-year-old man went to an ENT outpatient clinic because of stabbing pain in the left throat and difficult swallowing. He was found to have tonsillitis on the left and cervical lymphadenitis. The symptoms regressed on treatment with amoxycillin and clavulanic acid, but the cervical lymphadenitis persisted. Fine-needle biopsy of the cervical swelling was not diagnostic. Computed tomography of the neck showed an encapsulated liquid space-occupying lesion with infiltration of surrounding soft tissues.
  
  
  METHODS
  The cervical lymph-node mass was excised and histologically found to contain epithelioid granulomas with a few giant cells and scattered centrally caseous necroses. Tuberculostatic treatment was started; drainage fluid from the wound grew acid-fast bacilli, identified by gene probe as Mycobacterium gordonae.
  
  
  CONCLUSIONS
  Mycobacterium gordonae is ubiquitous in the environment and is being identified ever more frequently in microbiological laboratories, usually as contaminant. It rarely causes infections of soft tissues and the lungs or systemically.
