目的：检测肿瘤性肌上皮细胞标记物α－SMA 与雪旺细胞标记物 Leu －7在 ACC 中的表达。方法：免疫组织化学法检测 ACC 与粘液表皮样癌细胞中肌上皮细胞标记物α－SMA 蛋白与雪旺细胞标记物 Leu －7蛋白在病理切片中的表达。结果：Leu －7蛋白及 a －SMA 蛋白在 ACC 中存在共表达现象，提示二者分布在同种细胞中。结论：在 ACC 中 Leu －7蛋白及 a －SMA 蛋白存在共表达现象。%objective:Detection expression of myoepithelial cell marker α-SMA and the Schwann cell marker Leu -7 in the ACC.Methods:Immunohis-tochemical Detection expression of the myoepithelial cell marker α-SMA protein and Schwann cell marker Leu -7 protein in ACC and mucoepidermoid carcino-ma.Result:In the ACC both were observed phenomenon of tumor cells perineural invasion.Conclusion:ACC organizations has existed Schwann cell differenti-ation of the tumor cells.
