[Diaphyseal bone tuberculosis]

The authors report a case of diaphyseal bony tuberculosis, in which the diagnosis was not made for a long time as bony tuberculosis is considered exceptional and owing to the presence of a staphylococcus which oriented the diagnosis towards osteomyelitis. Bony tuberculosis certainly affects more easily immigrant patients, in whom one may see multifocal forms, but also affects those who, by their environment, might imagine they are protected, and it is not exceptional to see unifocal forms.
