Abstract
Osteosarcoma, the most common primary bone tumor in young individuals, frequently metastasizes hematogenously to the lungs, necessitating pulmonary metastasectomy as a common surgical procedure. While sublobar and lobar resections are accepted approaches, pneumonectomy is considered a major intervention. In this report, we present 2 intriguing cases of patients who underwent pneumonectomy for pulmonary osteosarcoma metastases, emphasizing the challenges of careful patient selection and surgical planning.
