摘要 目的探讨乳腺腺样囊性癌的临床病理特征。方法收集7例乳腺腺样囊性癌病例,分析其临床及病理资料。结果患者均为女性,年龄48~81岁,平均(67.1±9.76)岁,肿块最大径2.2~5 cm,中位最大径3cm。显微镜下观察,乳腺腺样囊性癌的形态结构多样,可见筛状、管状、实性结构,6例以筛状结构为主,1例以实性结构为主。肿瘤性肌上皮/基底细胞样细胞构成了肿瘤的主要成份,肿瘤性腺上皮数量少但一定存在。免疫组化示肌上皮/基底细胞样肿瘤细胞表达CK、CK5/6、Vimentin、P63、calponin。腺管上皮表达CK、CEA、EMA和CD117。Ki67指数5%~20%,中位数为10%。ER在7例均为阴性,6例PR阴性,1例阳性,HER2均为阴性。结论乳腺腺样囊性癌具有特征性的组织学形态和免疫表型,多属于基底细胞样癌。
