    [摘要] 目的 探讨含有微乳头状结构的乳腺单纯型黏液癌(MPMC)与乳腺单纯型黏液癌(PMC)的临床病理特征与预后差异。 方法 筛选2013年4月至2020年11月在本院确诊的31例PMC病例(MPMC 15例，PMC 16例)，對临床病理特征及预后进行分析。 结果 MPMC肿瘤直径更大，Luminal B型比例高(P<0.05)，MPMC中级别核级比例及淋巴结转移率呈增高趋势。两组脉管侵袭率、ER、PR和HER2、Ki67阳性率比较，差异无统计学意义(P>0.05)。两组各有1例复发转移，均无死亡病例。 结论 与PMC相比，MPMC侵袭力有一定程度的增加，两组预后无明显差异。

    [Abstract] Objective To investigate the difference in clinicopathological characteristics and prognosis between pure mucinous carcinoma of breast with micropapillary feature (MPMC) and pure mucinous carcinoma of breast (PMC). Methods A total of 31 PMC patients (15 MPMC patients and 16 PMC patients) diagnosed in our hospital from April 2013 to November 2020 were screened. The clinicopathological characteristics and prognosis were analyzed. Results The diameter of MPMC tumor was larger and proportion of Luminal B type was higher(P<0.05). The proportion of middle nuclear grade and rate of lymph node metastasis showed an increasing trend in MPMC. There were no statistical differences in vascular invasion rate ......
