摘要
３４例滑膜肉瘤，按ＷＨＯ１９６９年分型：双相型１４例，梭形细胞型１２例，上皮细胞型８例。免疫组化结果：Ｋｅｒａｔｉｎ阳性率７７．４％，Ｖｉｍｅｎｔｉｎ８０．６％。两者联合应用，对滑膜肉瘤特别是梭形细胞型的诊断和鉴别诊断很有价值。肥大细胞在滑膜肉瘤中是常见的，其阳性率为９１．１７％（３１／３４例）。但它的出现没有一定的规律性。滑膜肉瘤中钙化灶的多少与组织学类型有关，随着上皮成分的增加而增多。
Thirty four cases of synovial sarcoma, by the WHO criteria (1969), were classified into three histological types: 14 were biphasic, 12 spindle and 8 epithelial type. Immunohistochemical results showed that keratin positve rate was 77. 4% and vimentin 80. 6%. The keratin and vimentin were considered to be significant for the diagnosis and differentiation in synovial sarcoma of spindle cell type. Mast cells had been frenquetly found in synovial sarcomas ,its positive rate was 91. 17%, but the significance was not understood. The quantity of calcific foci was related to the histological type.
