Pulmonary infection due to Mycobacterium cosmeticum was reported in only two patients previously. More studies are warranted to define its characteristics and treatments. We report a systemic sclerosis patient who had a pulmonary infection due to M. cosmeticum and then successfully recovered after treatment with combination antibiotic regimen.
