摘要 目的探讨乳腺分泌基质的化生性癌(matrix-producing metaplastic carcinoma,MPMC)的临床病理学特征、免疫表型、诊断及鉴别诊断。方法对5例MPMC的临床特征及组织病理学进行观察,采用免疫组化SP法检测CK5/6、EGFR、S-100、p63、ER、PR及HER-2表达,并复习相关文献。结果5例女性乳腺癌患者,年龄32~62岁(平均51岁),3例病灶位于左侧,2例位于右侧,肿物呈结节状、膨胀性生长,边界较清,最大径1.4~3.5 cm。镜下见浸润性癌成分直接向黏液软骨样基质过渡,含黏液软骨样的基质与瘤细胞形成结节状,结节具有外周型和弥漫型两种生长模式,瘤细胞较小或呈多角形、梭形,核圆形或卵圆形,胞质较少。免疫表型:S-100阳性,CK5/6、EGFR大部分阳性,ER、PR、HER-2及p63阴性。5例中4例术后辅以化疗,1例术后未做治疗,目前患者均生存。结论MPMC属于三阴型乳腺癌,是一种极其罕见的乳腺化生性癌,需要与形态相似的乳腺肿瘤鉴别,结合特有的镜下形态及免疫组化标记可以明确诊断。
