Synovial sarcoma of the temporomandibular joint area: report of a case.
Synovial cell sarcoma is a relatively rare tumor of mesenchymal origin. It is a high-grade neoplasm that microscopically shows a monophasic or biphasic cellular pattern and includes epithelial features as well as supporting tissue features. Surgical excision is the primary mode of treatment. Postoperative radiotherapy and chemotherapy also is seen to be helpful. Between 3% and 10% of cases originate in the head and neck. A review of relevant literature shows less than 10 cases of synovial cell sarcoma of the temporomandibular joint area reported in the English literature. We report an additional case of biphasic synovial cell sarcoma arising in the temporomandibular joint area, which caused ear pain, tinnitus, and hearing loss, and we further discuss the clinical features, histopathology, differential diagnosis, and treatment modality.
