Primary pulmonary synovial sarcomas represent a rare clinical entity and account for approximately 0.5% of lung malignancies. We report the case of a 30-year-old male who presented clinically with haemothorax. Imaging revealed a complex collection obscuring a multi-lobulated mass in the right lower lobe of the lung. He underwent a right thoracotomy for evacuation of collection and surgical resection of his pulmonary mass. Histological analysis confirmed a grade 3 monophasic fibrous synovial sarcoma of the lung with infiltration to adjacent pleura, causing his initial haemothorax. Postoperative period was uneventful and patient was referred to the oncology team for further management. Primary pulmonary synovial sarcoma, though rare, should remain an important differential when considering lung malignancies, as complete surgical resection is the mainstay of treatment.
