Submandibular synovial sarcoma mimicking a vascular lesion: A rare case report

Abstract

Synovial sarcoma is a soft-tissue sarcoma of periarticular surfaces in close association with tendon sheaths, bursae, and joint capsules. Synovial sarcoma represents 5.6%–10% of all soft-tissue sarcomas. Knox suggested the name synovial sarcoma in the year 1936. These tumors are usually not found in soft tissues of head and neck region, and majority of tumors believed to take origin from paravertebral connective tissue spaces and manifest as parapharyngeal and solitary retropharyngeal masses near the carotid bifurcation. We present a rare case of biphasic synovial sarcoma of the submandibular region in a young male patient.
