Mycobacterium szulgai infection in the flexor sheath of the right index finger in an immunocompetent patient.

A 53-year-old woman was identified with Mycobacterium szulgai infection in the flexor sheath of the right index finger. Tissue was debrided at operation, and the patient was successfully treated with appropriate antimicrobials. M. szulgai is a rare cause of non-tubercular mycobacterium infection worldwide, and there are currently no clear guidelines on diagnosis and management. This is the first case reporting M. szulgai infection in the flexor sheath of the right index finger of a non-immunocompromised patient in the UK. 2017 BMJ Publishing Group Ltd.
