摘要 目的探讨Ber-EP4免疫组化染色在皮肤基底细胞癌中的表达及在鉴别诊断中的意义。方法收集本院近3年来病理确诊皮肤基底细胞癌患者20例作为研究组,并收集同时期病理确诊的其他皮肤病变35例作为对照组,全部病例均行常规苏木精-伊红染色和免疫组化Ber-EP4染色,并观察组织病理表现及免疫组化表达结果。结果研究组均可见肿瘤细胞与表皮基底部相连,均成团、巢或条索排列,细胞大小较一致、核质比增高,周边细胞呈栅栏状排列,可见核分裂象;免疫组化方面:研究组18例(90.0%)Ber-EP4呈阳性表达,其中2例为复发病例;对照组中7例(20%)Ber-EP4呈阳性表达,其中鳞癌和脂溢性角化病全部阴性。两组差异有统计学意义(P<0.01)。结论Ber-EP4对于皮肤基底细胞癌的诊断有一定价值,有助于基底细胞癌与皮肤鳞癌、脂溢性角化病的鉴别诊断。
