ABSTRACT

A lung tumor was detected in a 70-year-old-man in the course of investigation of metastasis from bladder carcinoma. He underwent a left lower lobectomy and was diagnosed with primary lung synovial sarcoma (pT2aN0M0-Stage IB).
Nine months after the surgery, he presented with dyspnea. Computed tomography revealed giant tumors (maximum 170 mm) in the form of pleural dissemination. Although the tumors progressed extremely rapidly, he was able to survive for 18 months after the recurrence due to chemotherapy. Primary lung synovial sarcoma is an extremely rare disease for which there is no established treatment. We herein report this case with a literature review.
