Mycobacterium abscessus, which is ubiquitous environmental organism, is more likely to cause pulmonary infection in the presence underlying lung disease and immunosuppression. We report a case of pulmonary disease due to coinfection of Mycobacterium tuberculosis (MTB) and Mycobacterium abscessus (M. abscessus) in an immunocompetent patient without underlying lung disease.Healthcare professionals should be aware of co-infection with MTB and M. abscessus, and treatment should be based on clinical suspicion and/or epidemiological circumstances.
