Synovial sarcoma of the frontal sinus. Case report.

Synovial sarcoma is a soft-tissue lesion occurring predominantly in the extremities of young adults. Although the head and neck region is the second most common site of involvement, synovial sarcoma has rarely been reported in the paranasal sinus. The authors present a case of synovial sarcoma arising from the frontal sinus and review the literature of synovial sarcomas arising from the paranasal sinuses.
