Abstract

Synovial sarcomas are rare soft tissue malignancies arising from tendons, tendon sheaths, and bursal structures. These tumors usually develop in the extremities of adolescents and young adults. Uncommonly, these tumors may arise in the head and neck approximately 9% of all synovial sarcomas. Most common sites of head and neck synovial sarcomas are hypopharynx and surrounding structures of paranasal sinuses. However, frontal bone without involving paranasal sinus is extremely rare. We report a case of biphasic synovial sarcoma of the frontal bone discuss the clinical and pathologic features of this case with the literature review.
