Primary orbital synovial sarcoma: a clinicopathologic review with a differential diagnosis and discussion of molecular genetics

Synovial sarcoma (SS) is a soft tissue sarcoma of the extremities developing in young adults that has rarely been reported in the orbit. SS is associated with a unique translocation, resulting in an SYT-SSX fusion gene. We analyze seven published periocular cases, together with the current one, to gain a better appreciation of the features of the tumor in this location and to compare the findings with those derived from non-ophthalmic studies. A 31-year-old woman developed an inferior orbital mass after experiencing periorbital and hemifacial pain for more than a decade.
