摘要 目的总结上皮样肉瘤的临床病理特点及诊断和鉴别诊断。方法对9例上皮样肉瘤患者的临床病理资料进行回顾性分析,用常规组织学和免疫组织化学进行光镜观察,并复习相关文献。结果 9例上皮样肉瘤中经典型5例,近端型4例。组织学:经典型常见肉芽肿样结构伴有中心坏死,主要由恶性上皮样细胞和梭形细胞组成;近端型呈多结节或弥散性结构,细胞由上皮样细胞或横纹肌样细胞组成,异型性明显,核分裂较多。两型免疫组化:细胞角蛋白CK(9/9)、上皮膜抗原EMA(8/9)、波形蛋白Vimentin(9/9),内皮细胞标记物CD34(5/9)、可容性酸性蛋白S100(2/9),不表达平滑肌肌动蛋白SMA、结蛋白Des、单链跨膜糖蛋白CD31和黑色素瘤HMB45。结论上皮样肉瘤比较罕见,组织学形态多样,诊断应密切结合临床特点和免疫组化结果。
