SummaryMycobacterium szulgai is a pathogenic organism that most frequently causes pulmonary infection and may rarely result in disseminated disease in immunocompromised individuals. We report a case of multifocal osteomyelitis and cutaneous lesions due to M. szulgai in a patient with chronic lymphocytic leukemia. The successful treatment of multifocal osteomyelitis was accomplished using isoniazid, rifampin, and ethambutol.
