Mycobacterial synovitis caused by slow-growing nonchromogenic species: Eighteen cases and a review of the literature

A heightened clinical suspicion for slow-growing nonchromogenic mycobacterial species is necessary when routine culture and histopathologic findings do not readily isolate an organism, or when the patient does not respond to antibiotic and anti-inflammatory treatment.
