Summary
This study reports the first orbital case of synovial sarcoma, a rare soft tissue cancer. Early recognition of this tumor is crucial, especially its spindle cell variant, to avoid misdiagnosis with less aggressive orbital neoplasms.
Area of Science:
- Ophthalmology
- Oncology
- Pathology
Background:
- Synovial sarcoma is a soft tissue malignancy predominantly affecting adolescents and young adults.
- Historically misattributed to synovial origins, its histogenesis is now understood differently.
- Orbital involvement represents an extremely rare presentation of this sarcoma.
Observation:
- A case of synovial sarcoma originating in the orbit is presented in a 21-year-old female.
- The initial presentation was a slowly growing subconjunctival mass.
- The tumor exhibited a typically biphasic morphology.
Findings:
- The monophasic spindle cell variant of synovial sarcoma can mimic other orbital connective tissue tumors.
- Accurate histopathological diagnosis is essential for appropriate management.
- This case highlights the potential for synovial sarcoma to arise in unusual locations like the orbit.
Implications:
- Increased awareness of orbital synovial sarcoma is needed among ophthalmologists and oncologists.
- Distinguishing this rare malignancy from benign orbital lesions is critical for patient outcomes.
- Further research into the behavior and treatment of orbital sarcomas is warranted.
