Synovial sarcoma of the mediastinum is a rare neoplasm that has overlapping histological and immunophenotypic features with other tumors in the differential diagnosis. We describe a case of this disease. The tumor was located at the right side of the pericardium, where an FDG‐PET scan showed an uptake. It was resected, a resection which was complicated by the necessity of partially resecting the pericaridium and right middle lobe which were invaded by the tumor. The doubling time of the main tumor [1] was 11.8 days. The margin of the resected specimen was tumor-free both macro- and microscopically. Reverse transcription-PCR confirmed the diagnosis of synovial sarcoma. The patient rejected chemotherapy or radiation therapy, and had recurrent tumors only one month after the operation. Finally, she opted to have only palliative care and died 79 days after the operation.
