Summary

A submental swelling mimicking a dental abscess was diagnosed as mycobacterial lymphadenitis. This highlights the importance of considering tuberculosis and non-tuberculous mycobacteria in differential diagnoses.

Area of Science:

  • Infectious Diseases
  • Pathology
  • Otolaryngology

Background:

  • Cervical lymphadenitis presents a diagnostic challenge, particularly when caused by non-tuberculous mycobacteria (NTM).
  • Mycobacterial infections can mimic common conditions like dental abscesses, complicating initial diagnosis.

Observation:

  • A 52-year-old female presented with a submental swelling initially suspected as a dental abscess.
  • Histopathology revealed lymphadenopathy with caseating granulomatous inflammation, indicating an infectious etiology.

Findings:

  • The inflammation was strongly suggestive of mycobacterial infection, specifically tuberculosis or NTM.
  • Non-tuberculous mycobacteria (NTM) cervical lymphadenitis poses diagnostic difficulties due to unreliable clinical and laboratory findings.

Implications:

  • Recognizing caseating granulomatous inflammation is crucial for diagnosing cervical lymphadenitis.
  • Dental surgeons play a key role in identifying systemic conditions like tuberculosis, especially in immigrant populations.
