摘要 目的探讨印戒样细胞变化与印戒细胞癌的组织学特点、免疫表型、诊断及鉴别诊断。方法对2例子宫颈癌中印戒样细胞进行病理学分析,采用免疫组化EnVision法检测CK、CK7、E-cadherin、CEA、p53、Ki-67、vimentin、p16、p63、ER、PR表达并复习相关文献。结果印戒样细胞变化与印戒细胞癌在形态上相似。印戒样细胞变化分非瘤性和肿瘤性印戒样细胞变化,子宫颈鳞癌和绒毛状管状腺癌可伴发非瘤性印戒样细胞变化。非瘤性印戒样细胞变化的细胞局限在基膜内,印戒细胞癌细胞在固有层内或更深组织内呈浸润性生长。非瘤性印戒样细胞变化免疫组化标记E-cadherin阳性,Ki-67低增殖指数和p53阴性,而印戒细胞癌E-cadherin阴性,Ki-67增殖指数高和p53阳性。肿瘤性印戒样细胞变化与肿瘤类型相关。结论印戒样细胞变化的细胞在形态上与印戒细胞癌细胞相似,需仔细观察组织学结构,并结合病变器官,借助于免疫组化(CK、E-cadherin、CEA、p53等)和特殊染色(D-PAS)有助于做出正确的诊断。
