Synovial sarcoma is a clinically rare, but morphologically well-defined neoplasm, which accounts for approximately 10% of all malignant soft-tissue tumors. The diagnosis can be established with clinical and imaging evaluations together with immunohistochemical, electron microscopy, and molecular genetic studies.


We describe a case of primary pulmonary synovial sarcoma presenting as a pneumothorax in a young woman at 34 weeks of gestation. Her persistent symptomatology ultimately led to a video-assisted thoracoscopy and thorascopic decortication. The diagnosis was established by pathology and immunohistochemistry of the cells, which were consistent with primary pulmonary synovial sarcoma.


Malignancies, even those as uncommon as primary synovial sarcoma, should be considered in the differential diagnosis of pneumothorax during pregnancy.
