Key result
Excision of a right main pulmonary artery mass in a 38-year-old male revealed an extremely rare primary pulmonary osteosarcoma with a predominant chondroblastic component.
Why the study?
Primary sarcomas of the pulmonary artery are extremely rare and often misdiagnosed as pulmonary thromboembolism, leading to ineffective anticoagulation treatment.
Case Report (n=1)
Primary osteosarcoma of the pulmonary artery is an extremely rare tumor that frequently masquerades as thromboembolic disease, requiring a high index of suspicion when patients are unresponsive to anticoagulation.

Primary pulmonary osteosarcoma warrants inclusion in differentials for pulmonary artery masses; extends sparse case literature but leaves optimal management undefined.
Primary sarcomas of pulmonary artery are extremely rare, highly malignant tumours and primary osteosarcoma of pulmonary artery is even rarer.Most of the cases are often misdiagnosed as pulmonary thromboembolism and anticoagulated to no effect.We present a case of 38-year-old male initially treated for infection and pulmonary thromboembolism but did not respond to antibiotics and anticoagulative measures.Chest radiograph revealed multiple lung nodules.Excision of right main pulmonary artery mass and upper lobe lung nodules was performed and was proven to be an osteogenic sarcoma of primary pulmonary artery on histopathological examination.

Ravindran et al. (2021) conducted a case report in Primary osteosarcoma of pulmonary artery (n=1). Excision of right main pulmonary artery mass and upper lobe lung nodules was evaluated on Histopathological diagnosis. Excision of a right main pulmonary artery mass in a 38-year-old male revealed an extremely rare primary pulmonary osteosarcoma with a predominant chondroblastic component.
