title: Nontuberculous mycobacterial adenitis of the head and neck in children: experience from a tertiary care pediatric center.
abstract: OBJECTIVE
  To describe our experience with the diagnosis, surgical treatment, and outcome of nontuberculous mycobacterial (NTM) adenitis of the head and neck in children, and to present a preliminary report about the use of NTM skin tests in our institution.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  The medical records of all children diagnosed with cervicofacial NTM adenitis were retrospectively reviewed for the period from January 1, 1995, through December 31, 2000. We also examined the use of intradermal skin tests for the diagnosis of NTM infection.
  
  
  RESULTS
  Fifty patients were diagnosed with NTM cervicofacial adenitis. Pertinent demographic information, clinical presentation, investigation, and type of diagnostic procedures were documented. Surgical procedures, complications, and relapses were also noted. One unusual case of retropharyngeal adenitis is illustrated. All patients were treated with complete excision of their lesion at the first operation. No major complications were noted. Only one patient relapsed and required a second operation. Forty-one children were skin-tested with NTM antigens. Of these, 30 patients were dual-tested with Purified Protein Derivative (PPD) also. No adverse reactions were noted with the use of skin tests. Sensitivity of NTM antigens alone is 87%. Sensitivity of dual testing is 78%. No patient had a PPD-dominant reaction.
  
  
  CONCLUSIONS
  Surgical excision is the treatment of choice of NTM adenitis because of the high cure rate with a single procedure, the excellent cosmetic result, and the low complication rate. NTM skin tests are safe and could be useful in early diagnosis of the infection but further investigation is needed.
