This study reports a rare case of monophasic synovial sarcoma (SS) in the mandible, a challenging diagnosis in unusual head and neck locations. This finding adds to the limited understanding of synovial sarcoma in the jaw area.
Area of Science:
- Oncology
- Pathology
- Head and Neck Surgery
Background:
- Synovial sarcoma (SS) is a soft tissue tumor, with 6-7% occurring in the head and neck.
- It predominantly affects young adults, with a slight male predominance.
- Common head and neck sites include the hypopharynx and parapharyngeal spaces.
Observation:
- Monophasic synovial sarcoma (MSS) diagnosis can be challenging, especially in uncommon locations.
- This article details a rare case of MSS originating in the mandible.
- The mandible is an extremely rare site for SS, with only six prior primary jaw involvements reported.
Findings:
- The case presented is the seventh reported instance of synovial sarcoma in the jaw.
- Histopathological and immunohistochemical analyses were crucial for diagnosis.
- Clinical features were compared with existing literature on rare SS presentations.
Implications:
- This case highlights the importance of considering MSS in the differential diagnosis of mandibular tumors.
- Further research into the specific characteristics and management of SS in unusual head and neck sites is warranted.
- Enhanced awareness among clinicians can improve early detection and patient outcomes for rare sarcomas.

Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
