Summary

A pediatric lymph node swelling was diagnosed as Mycobacterium bohemicum infection. This rare mycobacterial lymphadenitis highlights the importance of considering atypical infections in children.

Area of Science:

  • Pediatric Infectious Diseases
  • Microbiology
  • Histopathology

Background:

  • Submandibular swelling in children can be challenging to diagnose.
  • Cefaclor therapy is a common first-line treatment for bacterial lymphadenitis.
  • Persistent or atypical presentations warrant further investigation.

Observation:

  • A 2-year-old child presented with persistent right submandibular swelling.
  • The swelling did not resolve with standard oral antibiotic treatment (Cefaclor).
  • A lymph node excision was performed for diagnostic purposes.

Findings:

  • Histopathology confirmed granulomatous, partly necrotizing lymphadenitis.
  • A significant number of acid-fast bacilli were detected in the lymph node tissue.

  • Molecular techniques identified the causative agent as Mycobacterium bohemicum.

    • Implications:

    • Mycobacterium bohemicum is a rare cause of lymphadenitis in children.
    • This case underscores the need for considering atypical mycobacterial infections in pediatric lymphadenopathy.
    • Accurate identification through molecular methods is crucial for appropriate management of rare infections.
