摘要 目的探讨乳腺纤维腺瘤内低级别导管原位癌的临床病理学特征。方法收集深圳市第二人民医院2014年1月至2018年6月病理诊断为乳腺纤维腺瘤内低级别导管原位癌患者8例,总结临床病理资料并进行随访及预后分析。结果8例患者均为女性,发病年龄15~49岁,平均年龄35岁;体检乳腺可触及肿物,呈圆形,有弹性、活动度可;乳腺钼靶X线或彩超显示乳腺结节,边界清楚,提示纤维腺瘤。大体检查:圆形或类圆形结节,界限清楚,表面光滑,最大径1.2~2.8 cm,切面灰白、质中偏硬。镜下在纤维腺瘤背景内出现不典型细胞,呈拱桥状、筛状或实性排列;不典型细胞呈椭圆形或多角形,胞质丰富,细胞大小、形状及分布较一致,染色质均匀。纤维腺瘤内癌组织E-cadherin阳性,CK5/6阴性、雌激素受体(ER)同质性阳性,癌巢周围肌上皮p63、Calponin、CK5/6阳性。随访时间0.6~4年,8例均无复发。结论乳腺纤维腺瘤内低级别导管原位癌病理学形态表现为纤维腺瘤结节内出现的低级别导管原位癌,通过HE可确诊,必要时辅以免疫组织化学诊断。
