Mycobacterium kanasii flexor tenosynovitis of the finger.

ABSTRACT

We report an extreme case of Mycobacterium kanasii flexor tenosynovitis with flexor tendon rupture in a healthy 65-year-old left-hand dominant Caucasian housewife. This case highlights the diagnostic conundrum of atypical mycobacteria infections due to their insidious presentation, the need for a high index of suspicion to prevent worsening or delaying the diagnosis from inappropriate steroid use and that these infections can occur in otherwise healthy individuals.
