【摘要】：正原发性肺黏液表皮样癌(pulmonary mucoepidermoid carcinoma,PMEC)是一种涎腺型恶性肿瘤,在所有肺癌的占比不足1%,由黏液细胞、中间型细胞和表皮样细胞构成。根据组织形态学和细胞形态学特征,其可分为低级别和高级别两大类[1]。PMEC因发病率极低,以往的报道多为个案报道或是小样本研究,临床表现不具备特异性,病理组织学上易误诊。有文献[2-3]报道PMEC中存在表皮生长因子受
[Abstract]:Positive primary pulmonary mucoepidermoid carcinoma (pulmonary mucoepidermoid carcinoma,PMEC) is a malignant tumor of the salivary gland, which accounts for less than 1% of all lung cancer and is composed of mucinous cells, intermediate cells and epidermoid cells. According to the characteristics of histomorphology and cell morphology, PMEC can be divided into two categories: low grade and high grade [1]. Because of the very low incidence of PMEC, most of the previous reports are case reports or small sample studies, and the clinical manifestations are not specific. Histologically, it is easy to misdiagnose. It has been reported in the literature [2 鈮，
