Summary

A patient presented with an inguinal mass that was diagnosed as Mycobacterium avium-intracellulare (MAI) infection. Despite CD4 lymphopenia, HIV testing remained negative, suggesting MAI can cause lymphopenia without HIV.

Area of Science:

  • Infectious Diseases
  • Immunology
  • Surgical Pathology

Background:

  • A 44-year-old male motorcyclist presented with a painful, irreducible inguinal mass.
  • Previous lung biopsy in 1998 showed miliary granuloma.

Observation:

  • Exploration revealed no hernia; incision of the mass identified acid-fast bacilli.
  • Subsequent culture confirmed Mycobacterium avium-intracellulare (MAI) as the causative agent.

Findings:

  • Blood tests revealed CD4 lymphopenia.
  • Human Immunodeficiency Virus (HIV) testing was negative at presentation and remained so two years later.

Implications:

  • This case highlights MAI as a potential cause of inguinal masses and CD4 lymphopenia in immunocompetent individuals.

  • It underscores the importance of considering atypical mycobacterial infections in the differential diagnosis of unexplained lymphopenia and localized masses.
