摘要 目的:探讨肺原发滑膜肉瘤的临床病理学特征、诊断及鉴别诊断特点。方法:对5例肺原发滑膜肉瘤的组织学形态、免疫组织化学、SYT-SSX mRNA进行观察及检测,并结合文献进行复习。结果:肺原发滑膜肉瘤为圆形或结节状肿块,灰白色,质中等或偏软,部分鱼肉状有囊性变及坏死;组织学单相梭形细胞型3例,双相型1例,低分化小细胞型1例;免疫组织化学检测5例均见EMA、VIM及CD99表达,4例CKpan、CK7、CK19、Bcl-2不同程度的表达,而MyoD1、MSA、SMA、HMB45、CD117、CAL、TTF-1均未见表达,其中2例用RT-PCR法行STY-SSX融合基因检测均见STY-SSX mRNA表达。结论:肺原发滑膜肉瘤是一种少见的肿瘤,在诊断、鉴别诊断中应注意和转移性滑膜肉瘤及其他肿瘤区别,免疫组织化学和STY-SSX融合基因检测有助于诊断。
