乳腺肌上皮癌2例
Chinese Journal of Diagnostic Pathology（2018）
Abstract
乳腺肌上皮癌(myoepithelial carcinoma,MEC)是一种发生于乳腺的罕见恶性肿瘤.WHO(2003)乳腺和女性生殖系统肿瘤病理学与遗传学分类[1]将其归为肌上皮病变(myoepithelial lesions,MEL),又称恶性肌上皮瘤(malignant myoepithelioma,MME);WHO(2012)乳腺肿瘤分类[2]将MEC归入化生性癌,只在梭形细胞癌(spindle cell carcinoma,SCC)中提及该名称.该瘤临床少见,且ER、PR和c-erbB-2/Her-2阴性.本文报道2例MEC,从临床特点、组织形态学特征和免疫表型进行分析并复习相关文献,以期提高对MEC的认识.
