Synovial Sarcoma of the Lung- An Unusual Tumor with Atypical Presentation

A BSTRACT Synovial Sarcoma (SS) is a rare malignant mesenchymal tumor and has been classified as a separate entity by the WHO, constituting 0.1%–0.5% of all primary lung malignancies. It can develop at any anatomic site. Most primary lung cases present with chest pain, cough, and large intrathoracic mass. A multimodality approach with lobectomy/pneumonectomy with or without chemotherapy and radiation is the standard management. We hereby present a rare case of SS of the lung, posing a diagnostic dilemma in an elderly male in his late 80’s. The diagnosis was made using endobronchial ultrasound, resected specimen’s histopathological analysis and immunohistochemistry.
