Flexor Tenosynovitis Caused by Mycobacterium arupense: A Case Report and Review of the Literature

JBJS Case Connect. 2020 Jul-Sep;10(3):e20.00033. doi: 10.2106/JBJS.CC.20.00033.

Abstract

Case: A 64-year-old man presented with swelling of his right hand and forearm. This swelling had been recurring for 5 years. He liked sea fishing and frequently injured his fingers with fishhooks. He had difficulty bending his right little and ring fingers for 2 years and experienced finger numbness for several months. We diagnosed nontuberculous mycobacterial flexor tenosynovitis after Mycobacterium arupense was detected in a tissue sample. After surgery and 2 years of multidrug therapy, he has been recurrence-free for 3 years.

Conclusion: Nontuberculous mycobacteriosis should be considered in chronic tenosynovitis cases.
