Treatment of Lymphadenitis

Introduction to Lymphadenitis Treatment

  • The American Thoracic Society recommends that the treatment for lymphadenitis depends on the causative organism, with surgical excision being the primary treatment for non-tuberculous mycobacterial (NTM) lymphadenitis, while bacterial lymphadenitis typically requires appropriate antibiotic therapy based on the suspected pathogen 1

Non-Tuberculous Mycobacterial (NTM) Lymphadenitis

  • The American Thoracic Society recommends excisional surgery without chemotherapy as the treatment for children with NTM cervical lymphadenitis, with a success rate of approximately 95% 1
  • Incisional biopsy alone or anti-TB drugs without macrolides should be avoided as they frequently lead to persistent disease, sinus tract formation, and chronic drainage 1
  • For recurrent disease or when surgical risk is high, a clarithromycin-based multidrug regimen may be considered 1
  • The American Thoracic Society advises against incisional biopsy alone for NTM lymphadenitis as it can lead to chronic drainage and sinus tract formation 1
  • The American Thoracic Society recommends not relying solely on anti-TB drugs without macrolides for NTM lymphadenitis 1

Borrelial Lymphocytoma (Lyme Disease)

  • For patients with borrelial lymphocytoma, oral antibiotic therapy for 14 days is recommended 2
  • Oral antibiotic options include doxycycline, amoxicillin, or cefuroxime axetil, as recommended by the Infectious Diseases Society of America 3

Special Considerations

  • In cases where TB is suspected, the American Thoracic Society recommends initiating anti-TB therapy while awaiting culture results, especially when risk factors for TB are present 1
