Summary
A persistent finger tenosynovitis case was diagnosed as osteomyelitis caused by Mycobacterium arupense after a year of workup. This rare infection presents diagnostic and treatment challenges due to limited data.
Area of Science:
- Infectious Diseases
- Orthopedics
- Microbiology
Background:
- Tenosynovitis can be a persistent and challenging condition.
- Mycobacterium arupense is a rare pathogen with limited documented human infections.
Observation:
- A 50-year-old man presented with persistent tenosynovitis in his right fourth finger.
- Extensive workup over nearly a year was required for diagnosis.
Findings:
- The cause of tenosynovitis was identified as osteomyelitis due to Mycobacterium arupense.
- Literature review revealed associations with trauma, environmental exposure, and delayed diagnosis in similar cases.
Implications:
- Accurate and timely diagnosis of Mycobacterium arupense infections is crucial.
- Treatment strategies require further investigation due to limited antimicrobial susceptibility data.
- This case highlights the importance of considering atypical mycobacterial infections in persistent musculoskeletal conditions.

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
