[Mycobacterium malmoense infection in an immunocompetent patient]

We report the case of a 57-year-old patient in whom we found a pulmonary infection due to Mycobacterium malmoense. This patient had no immunodeficiency and responded quite rapidly to anti-tuberculous therapy. He was treated for 6 months by levofloxacine, myambutol, and nicotibine, followed by 3 months of clarithromycine, levofloxacine and myambutol. The patient improved clinically to become asymptomatic and the cavitary lesion shown at the CT-scan slightly decreased. The patient is still currently treated by clarithromycine and ciproxine.
