Primary pleural synovial sarcoma is a malignant tumour and thought to be more aggressive than synovial sarcoma which occurs in extremities. Its treatment strategy has not been fully established because of its rarity. We report a primary pleural synovial sarcoma case which achieved a long‐term survival with repeated surgery of recurrent pleural tumour. A 39‐year‐old man presented with a gradually enlarged tumour in the left hemithorax. The tumour was resected and diagnosed as primary pleural synovial sarcoma. The tumour was slowly growing and repeatedly recurrent in the left pleura. The surgical resections for the recurrent tumours were performed 6 years and 11 years after the initial surgery. Intriguingly, recurrent tumour which developed after second surgery exhibited temporally spontaneous regression. Our patient remains alive 12 years after the initial surgery. Repeated resection of metastatic lesion can achieve long survival in primary pleural synovial sarcoma.
