Excision of recurrent synovial sarcoma of the infratemporal fossa.

Synovial sarcoma is a soft tissue sarcoma especially encountered in the lower extremities. The infratemporal fossa is quite a rare location. Since it is a closed location, combined approaches and multidisciplinary planning always need to be considered. This case emphasizes the high-grade character of synovial sarcoma, which causes it to recur often. The difficulty of clear surgical margins in the infratemporal fossa adds to synovial sarcoma a second challenging issue. Therefore, the need of complementary therapy is essential. In this case, we applied postoperative radiotherapy and we did not observe any sign of local, regional or distant metastasis in the one-year follow-up. In this article, we present a 68-year-old male patient together with totally excised synovial sarcoma in the infratemporal fossa by mandibular swing and transzygomatic technique information on the manifestation, imaging, histopathological features and postoperative complications of previous infratemporal fossa synovial sarcomas.
