    Summary
    This summary is machine-generated.

    Mycobacterium terrae complex is a rare cause of tenosynovitis in the forearm and hand, typically resulting from direct inoculation. This infection appears localized and can affect healthy individuals.

    Area of Science:

    • Infectious Diseases
    • Microbiology
    • Dermatology

    Background:

    • Tenosynovitis, an inflammation of the tendon sheath, can have various etiologies.
    • Mycobacterial infections are uncommon causes of tenosynovitis, particularly in immunocompetent individuals.
    • Mycobacterium terrae complex is a rarely reported pathogen in human infections.

    Observation:

    • A 72-year-old male presented with tenosynovitis affecting the left forearm and hand.
    • Histopathological analysis of excised tissue revealed noncaseating granulomas.
    • Mycobacterial cultures identified the causative agent as Mycobacterium terrae complex.

    Findings:

    • This case, along with a review of four previously documented cases, suggests Mycobacterium terrae complex primarily causes localized infections in the forearm and hand.

  • Infection appears to occur via direct inoculation.
  • Systemic dissemination from the initial site of infection was not observed in any of the reported cases.
  • Implications:

    • Mycobacterium terrae complex should be considered in the differential diagnosis of tenosynovitis, especially after potential direct inoculation.
    • The organism may cause infection in individuals without apparent underlying health issues.
    • Further research into the pathogenesis and treatment of Mycobacterium terrae complex infections is warranted.
