Metastasectomy and aggressive induction chemotherapy are the 2 most well-known treatment options. However, reactivation of pulmonary tuberculosis can be a problem in developing countries, where the prevalence of tuberculosis is high. Here, we described a patient with osteosarcoma with pulmonary tuberculosis reactivation mimicking metastasis.
