Mycobacterium arupense finger osteomyelitis: Case report.

We describe a case of persistent tenosynovitis in the right fourth finger of a 50-year-old man that after almost a year of workup was found to be related to osteomyelitis caused by Mycobacterium arupense. The few cases found in the literature were associated with traumatic injuries, environmental contamination, and months of misdiagnosis. Treatment is challenging as there are limited data available on antimicrobial susceptibility and potential side effects of current therapy options.
