Synovial Sarcoma is a soft tissue neoplasm having incidence 6%- 10%.Malignant cells in synovial fluid aspiration is extremely rare. Only 5%cases have been reported to have joint cavity involvement. We report a case of synovial fluid malignant effusion of knee joint in a 35 year old male who presented with a left popliteal fossa swelling. Biphenotypic sinonasal sarcoma is a newly recognized, very rare, low grade malignant tumor of the nasal cavity which was formerly probably included in fibrosarcoma and synovial sarcoma cases. It was incorporated into the fourth edition of the World Health Organization Classification of Head and Neck Tumours, published in 2017. Scandinavian Sarcoma Group (SSG) on synovial sarcomas were compared to the intra-articularsynovial sarcomas. 2.

Synovial sarcoma mostly affects extremities, more commonly lower extremities, but rarely may it may be seen in head, neck, thorax, and abdomen. Synovial sarcoma: Almost histologically identical, but genetic translocation (SS18-SSX1 or SSX2) will be shown through FISH or RT-PCR.

1.Introduction Soft-tissue synovial sarcomas commonly arise in paraar-ticular locations of the extremities but are rarely found in the lungs. Primary pulmonary synovial sarcoma is an aggressive tumor accounting for approximately 0.05% of all primary lung malignancies [1, 2]. The most common rovascular complex.9,10 On MRI, renal synovial sarcomas are often described as nonspecific heterogeneous masses, although they may also exhibit heterogeneous enhance-ment of hemorrhagic areas, calcifications, and air-fluid lev-els (known as “triple sign”) as well as septae. The triple sign The incidence of synovial sarcoma arising in a joint has been unknown but believed to be low . According to our data the incidence of intra-articular synovial sarcomas is 3% of all synovial sarcomas. The overall disease-free survival for intra-articular synovial sarcomas was 86% and for all synovial sarcomas 54%.
 Histologically, synovial sarcomas are differenti-ated into four subtypes: monophasic, monophasic epithelial, biphasic, and poorly differentiated types. [10,11] The present case was classified as poorly dif-ferentiated synovial sarcoma because cystic, solid component and intratumoral hematoma were ob-served. Shows multiloculated, heterogeneous mass. “Triple Signal Intensity sign”; hypointense, isointense and hyperintense with fat on T2 – weighted MRI imaging. This

Synovial sarcomas are frequently multilobulated, and areas of necrosis, hemorrhage, and cyst formation are also common. Fig. 1 There are three main histologic subtypes of synovial sarcoma: biphasic, monophasic, and poorly differentiated. Monophasic synovial sarcoma represents 50%-60% (the most common subtype) of all

The name "synovial sarcoma" was coined early in the 20th century, as some researchers thought that the microscopic similarity of some tumors to synovium, and its propensity to arise adjacent to joints, indicated a synovial origin; however, the actual cells from which the tumor develops are unknown Synovial sarcoma. Synovial sarcoma is a rare type of cancer that tends to arise near large joints, particularly the knee, in young adults. Despite its name, it typically doesn't affect the interior of joints, where synovial tissue and fluid are located. The first sign of trouble is usually a deep-seated lump that may be tender or painful. The name "synovial sarcoma" was coined early in the 20th century, as some researchers thought that the microscopic similarity of some tumors to synovium, and its propensity to arise adjacent to joints, indicated a synovial origin; however, the actual cells from which the tumor develops are unknown and not necessarily synovial. DIAGNOSIS Synovial sarcoma Differential diagnosis: Malignant fibrous histocytoma, fibrosarcoma, liposarcoma, osteosarcoma, and chon-drosarcoma.

Patients with synovial cell sarcoma are often between the ages of 15 and 35 years old; generally younger than patients with other types of soft tissue sarcomas. and mediastinal synovial sarcoma shows less vascularity and a similar triple sign (bright, dark and gray) representing tumor, hemorrhage, and necrosis on magnetic resonance imaging. The T2 weighted images on MRI demonstrate well the so called” triple sign”.
