摘　　要：淋巴结转移率高、预后差是乳腺浸润性微小乳头状癌的独特生物学行为。通过光镜下观察到肿瘤细胞聚集成微乳头状，以及免疫组化上皮膜抗原（EMA）强表达是准确及时诊断该类型肿瘤的可靠方法。相比较以往的诊断标准，最近提出的新标准更加重视乳腺浸润性微小乳头状癌的诊断，因而对这类患者的治疗及预后判断有重要的意义。Invasive micropapillary carcinoma of breast is associated with poor prognosis and high incidence of lymph node metastasis. Tumor cells are observed as micro- papillary with light microscope. And high expression of epithelial membrane antigen（EMA） examined by immunohistochemistry is a reliable way of diagnosing this carcinoma accurately and timely. Compared with the previous diagnostic criteria, the new criteria pays more attention to the diagnosis of invasive micropapillary carcinoma of the breast. For this reason, it has important significance for treatment and prognosis of patients with invasive micropapillary carcinoma of the breast.
