Successful treatment of mycobacterium avium osteomyelitis and arthritis in a non-immunocompromised child.

In non-immunocompromised children, infections with mycobacterium avium complex (MAC) are rare, except for cervical lymphadenitis. We report here a 34-month-old boy who developed osteomyelitis and septic arthritis due to MAC. No findings could be revealed for immunodeficiency. He was treated successfully for 12 months with combined therapy consisting of clarithromycin, rifabutin and protionamid.
