A recent case report highlights a rare GLI1-altered mesenchymal tumor presenting in the pleura (lining of the lung), a location where tumors can closely resemble synovial sarcoma. This case underscores a critical challenge in rare cancers — different tumors can appear similar under imaging and even under the microscope, making accurate diagnosis essential for appropriate […]
Advances in cell therapy for synovial sarcoma are creating more treatment options for patients with advanced disease. A recent update from Penn Medicine highlights the growing role of T-cell therapies in treating rare cancers like synovial sarcoma. What Is Afami-cel? Afamitresgene autoleucel (afami-cel) is the first FDA-approved T-cell receptor (TCR) therapy for adults with advanced […]
Synovial sarcoma is a rare soft tissue cancer that usually develops near joints in the arms or legs. However, in very rare cases, it can appear in unexpected places — including the pericardium, the lining around the heart. A recent case report describes a 23-year-old patient diagnosed with primary pericardial synovial sarcoma, an extremely uncommon […]
Synovial sarcoma is a rare soft tissue cancer that most commonly develops near the joints of the arms or legs. In extremely rare cases, it can arise in unexpected locations — including the heart. A recent case report highlights primary cardiac synovial sarcoma, an exceptionally uncommon presentation that underscores the complexity of diagnosing and treating […]
A recent case report describes a rare but serious complication in a patient with metastatic synovial sarcoma of the lung—highlighting the importance of infection monitoring following thoracic surgery. The case focuses on pleural aspergillosis, an uncommon fungal infection that can occur in immunocompromised patients, particularly after lung surgery. A Complex Clinical Course A 28-year-old patient […]
A recent case report describes an extremely rare solitary fibrous tumor (SFT) occurring in the maxilla (upper jaw), highlighting the importance of accurate diagnosis in rare soft tissue tumors. Although SFT is different from synovial sarcoma, both are rare mesenchymal tumors that can present similarly, making diagnosis dependent on specialized testing. A Rare Presentation A […]
Most synovial sarcoma tumors develop in the soft tissues near the joints of the arms or legs in adolescents and young adults. However, physicians occasionally encounter rare presentations in other organs. A recent case report describes primary synovial sarcoma of the lung in a young child, highlighting how difficult rare pediatric sarcomas can be to […]
Synovial sarcoma is a rare soft tissue sarcoma most commonly treated with surgery, chemotherapy, radiation therapy, and targeted drugs such as pazopanib. However, treatment options can be limited for advanced or metastatic disease. A recently published case report describes a patient with synovial sarcoma who achieved a complete response after receiving targeted therapy based on […]
On February 19, 2026, the Synovial Sarcoma Foundation brought together patients, families, clinicians, and researchers from around the world for its second community webinar—an evening focused on progress, partnership, and hope. The full webinar recording is available to watch below: The webinar was moderated by Nathan Imperiale, Chairman of the Board, and featured: Highlights Foundation […]
Synovial sarcoma is driven by a defining genetic event — the SS18-SSX fusion protein, present in nearly all cases. For years, research and therapeutic development have focused on how this fusion interacts with the SWI/SNF chromatin remodeling complex, believed to play a central role in tumor growth. However, newly published research challenges that long-standing assumption […]
