Joints and adjacent tissue are probably the site of origin of synovial sarcomas. From the literature review, however, it appears that in some instances synovial sarcoma may be of extra-articular soft tissue origin. This type of tumor should be considered highly malignant. It appears that the incidence is low among black Americans. The etiology is not known definitely, but trauma is incidental rather than a predisposing factor.
关节及相邻组织可能是滑膜肉瘤的起源部位。然而，从文献综述来看，在某些情况下，滑膜肉瘤可能起源于关节外软组织。这种类型的肿瘤应被视为高度恶性。在美国黑人中，其发病率似乎较低。病因尚不完全明确，但创伤只是偶然因素，而非诱发因素。
