BACKGROUND Synovial sarcoma is a rarely encountered soft tissue sarcoma. Surgery with a wide surgical margin is the treatment of choice. However, there is no consensus on the treatment of head and neck synovial sarcoma in patients with cervical metastasis. METHODS A 20-year-old man was seen with a palpable mass in the right neck. He had been diagnosed with synovial sarcoma of the right tonsil...

Introduction: Synovial sarcoma makes up 8–10% of all soft tissue sarcomas, and constitutes 3–10% of all sarcomas occurring in the head and neck region. It shows male predominance (3:2), and the mean age of presentation is 30 years.   Case Report: A 51-year-old gentleman presented with right-sided neck swelling which had been progressively increasing in size for the past 2 years. A computed ...

Background: Synovial sarcoma is one of the rarest soft tissue tumor with a high grade malignancy. Primary synovial chest wall rare.
 Presentation case: A 65-year-old woman presented history left upper mass previously operated 9 months ago. The pathological report was sarcoma. Computed tomography done and revealed RT anterior infraclavicular cystic solid lesions measuring 8.5 *3.5*4 cm.&#x0...

Synovial sarcoma is a rare soft tissue sarcoma that typically arises in the extremities of young adults. We report a case of a 26-year-old pregnant woman with biopsy-proven primary synovial sarcoma of the lung that was treated with chemotherapy with radiographic response. This is only the third documented case of primary pulmonary synovial sarcoma occurring during pregnancy and the first case w...

Synovial sarcoma is an aggressive soft-tissue malignancy marked by a unique t(X;18) translocation leading to expression of a chimeric SYT-SSX fusion protein. We report here a mouse model of synovial sarcoma based on conditional expression of the human SYT-SSX2. Using this model, we have identified myoblasts as a potential source of synovial sarcoma. Remarkably, within the skeletal muscle lineag...

Synovial sarcoma of lung is a rare tumor with few case reports in literature. Though named synovial sarcoma due to its resemblance to synovium on light microscopy, it arises from mesenchymal tissue. Here, we present a case of synovial sarcoma of lung in a 7-year old boy, with main emphasis on difficulty faced in the management.

Synovial sarcoma is a rare type of soft tissue sarcoma that arises in tissues containing synovial fluid, usually in the extremities. It has only rare occurrence in the retroperitoneal space. Early detection of retroperitoneal synovial sarcoma is difficult, since the retroperitoneal space is highly expandable and deeply hidden. Furthermore, the presenting symptoms are often vague and nonspecific...

We report a case of a 19-year-old woman with a primary pericardial synovial sarcoma that extended from the right ventricular free wall to the posterior aspect of the left anterior thoracic wall. Synovial sarcoma was diagnosed by the detection of the chimeric transcript SYT-SSX using reverse transcriptase-polymerase chain reaction (RT-PCR). This transcript is generated by reciprocal translocatio...

Reprint requests to: Dr. Michael Mu Huo Teng Department of Radiology, Taipei Veterans General Hospital. No. 201, Shih Pai Road, Taipei 112, Taiwan, R.O.C. Synovial sarcoma is a rare and aggressive soft tissue tumor with extensive metastatic potential. It accounts between 8 and 10% of all soft tissue malignancies. Involvement of the head and neck region is relatively rare. We report a case of sy...

Synovial sarcoma is a primitive mesenchymal tumor which occurs most frequently in soft tissues. Some unusual locations of synovial sarcoma could lead to diagnostic challenges. In this study, we reported a case of primary synovial sarcoma arose in the posterior pharyngeal wall. X-ray examination showed a space-occupying lesion in the post-pharyngeal wall. Frozen section and conventional histopat...
