Primary pulmonary synovial sarcoma: How to expect the unexpected?

Abstract

Primary pulmonary synovial sarcoma (PPSS) is a rare and aggressive malignancy with a presentation similar to that of lung carcinoma. We present an 18-year-old male who presented with complaints of chest pain, cough, and hemoptysis. Physical examination and blood parameters were normal. Imaging studies revealed a large, well-defined, round homogeneous mass in the left lower lobe. His fine-needle aspiration cytology was suggestive of a round cell tumor. The patient was operated under general anesthesia through left posterolateral thoracotomy. The tumor was removed en masse and sent for histopathological examination. His histopathology and immunohistochemistry suggested PPSS of biphasic variety.
