Primary monophasic synovial sarcoma of the pleura: Neoadjuvant chemotherapy followed by complete resection.

We describe a rare case of primary pleural synovial sarcoma in a 27-year-old man with a 4-month history of dry cough and left-sided chest pain. A CT scan showed a large cystic mass in the left pleural cavity. The patient underwent two video-assisted thoracoscopic biopsies and the diagnosis of synovial sarcoma of the pleura was established. After neoadjuvant chemotherapy, which resulted in a partial response, the tumor was completely resected with extrapleural pneumonectomy. Pathological findings showed less than 5% of viable cancer and free surgical margins. The patient is clinically well 24 months after surgery, with no evidence of recurrent disease. © Tianjin Lung Cancer Institute and Blackwell Publishing Asia Pty. Ltd.
