A case of intra-articular calcifying synovial sarcoma of the right knee joint in a 27-year-old man is reported. Prior to admission the patient had been suffering pain in the right knee for 5 years. Plain radiographs showed multiple calcified densities in the anterior aspect of the right knee closely mimicking synovial chondromatosis. Histological examination revealed that the lesion was a synovial sarcoma with extensive calcification subjacent to the synovial surface. Although intra-articular calcifying synovial sarcoma is very rare, it is important to be aware of the fact that synovial sarcoma, as well as synovial chondromatosis, can be present as a calcified lesion in the joint cavity.
报告了一例27岁男性右膝关节关节内钙化性滑膜肉瘤病例。入院前患者右膝疼痛5年。X线平片显示右膝前部有多个钙化灶，酷似滑膜软骨瘤病。组织学检查显示病变为滑膜肉瘤，滑膜表面下方有广泛钙化。尽管关节内钙化性滑膜肉瘤非常罕见，但必须认识到滑膜肉瘤以及滑膜软骨瘤病都可能表现为关节腔内的钙化性病变。
