Is synovial sarcoma biphasic?
Histologically, synovial sarcoma is characterized by epithelial-like and spindle cell components arranged in a biphasic or monophasic pattern, and a poorly differentiated form of synovial sarcoma has also been described recently [6]. The pathologic features of synovial sarcoma are identical in children and adults.
Does sarcoma cause multiple lumps?
They often begin as a small growth or bump, and are usually painless. Sometimes, there are open sores on the skin above the tumor that may be mistaken for areas of infection. Eventually, multiple growths or bumps may develop. Epithelioid sarcoma can move into nearby tissue and spread to other areas of the body.
What type of cancer is synovial sarcoma?
Synovial sarcoma is a cancer that can come from different types of soft tissue, such as muscle or ligaments. It is often found in the arm, leg, or foot, and near joints such as the wrist or ankle. It can also form in soft tissues in the lung or abdomen. Synovial sarcoma may also be called malignant synovioma.
What is biphasic synovial sarcoma?
Biphasic synovial sarcoma often shows irregular-shaped glandular structures dispersed in a monomorphic spindle cell component. The epithelial cell nuclei are rounded and relatively uniform. Monophasic SS is composed of irregular small short or ovoid spindle cells with apparently overlapping vesicular nuclei.
Can Stage 4 synovial sarcoma be cured?
A sarcoma is considered stage IV when it has spread to distant parts of the body. Stage IV sarcomas are rarely curable. But some patients may be cured if the main (primary) tumor and all of the areas of cancer spread (metastases) can be removed by surgery. The best success rate is when it has spread only to the lungs.
Is it possible to have multiple sarcomas?
Developing multiple soft tissue sarcomas (STSs) is a rare process, sparsely reported in the literature to date. Little is known about the pattern of disease development or outcomes in these patients.
Can you have a cancerous lump for years?
For example, certain types of skin cancer can be diagnosed initially just by visual inspection — though a biopsy is necessary to confirm the diagnosis. But other cancers can form and grow undetected for 10 years or more , as one study found, making diagnosis and treatment that much more difficult.
How long can you live with metastatic sarcoma?
5-year relative survival rates for soft tissue sarcoma
| SEER Stage | 5-Year Relative Survival Rate |
|---|---|
| Localized | 81% |
| Regional | 56% |
| Distant | 15% |
| All SEER stages combined | 65% |
How long does it take sarcoma to spread?
Delays between tumor recognition by a patient to diagnosis were between 1 and 3 years in most cases. However, in three cases of synovial sarcoma, it took more than 10 years to reach a diagnosis, and in another case of synovial sarcoma, it took more than 5 years.
Can a synovial sarcoma occur in the head?
However, it also can occur in the head, neck and trunk. We spoke with Dejka M. Araujo, M.D., and sarcoma research intern Michelle G. Yeagley to learn more about diagnosis, treatment options and the latest research on synovial sarcoma. What are common synovial sarcoma symptoms?
When does synovial sarcoma fusion of SS18 occur?
E. Synovial sarcoma has fusion of SS18 with SSX1, SSX2 or SSX4. It typically occurs in younger patients, with the peak incidence in the third – fourth decade and most cases show at least focal cytokeratin expression. It is not associated with PAX3 rearrangements, a typical finding in alveolar rhabdomyosarcoma…
What kind of morphologies are found in synovial sarcoma?

Which is better to grade synovial sarcoma or fnclcc?
Stronger E-cadherin and increased extracellular matrix protein MMP2 expression are needed for biphasic morphology to develop In children: new grading system by the Pediatric Oncology Group (POG) for nonrhabdomyosarcoma soft tissue sarcoma in children showed discrepant higher grading for synovial sarcoma compared to FNCLCC
