Metastatic pulmonary synovial sarcoma: A double coincidence: Case report

Area of Science:

• Oncology
• Pathology

Background:

• Synovial sarcoma is an aggressive soft tissue neoplasm, typically affecting extremities.
• Pulmonary involvement is exceptionally rare, posing diagnostic challenges.

Observation:

• A 34-year-old woman presented with chest pain and a large right hemi-thorax mass on radiography.
• CT imaging revealed bilateral renal metastases, initially suggesting a primary pulmonary malignancy or spindle-cell carcinoma.

Findings:

• Post-operative pathological analysis confirmed the chest mass as a primary pulmonary synovial sarcoma.
• The case highlights the unusual presentation and metastatic potential of this rare sarcoma.

Implications:

• This case expands the known clinical spectrum of synovial sarcoma.
• It underscores the importance of considering rare diagnoses in challenging presentations of thoracic masses with metastasis.
