【摘要】：正原發(fā)性肺黏液表皮樣癌(pulmonary mucoepidermoid carcinoma,PMEC)是一種涎腺型惡性腫瘤,在所有肺癌的占比不足1%,由黏液細(xì)胞、中間型細(xì)胞和表皮樣細(xì)胞構(gòu)成。根據(jù)組織形態(tài)學(xué)和細(xì)胞形態(tài)學(xué)特征,其可分為低級(jí)別和高級(jí)別兩大類[1]。PMEC因發(fā)病率極低,以往的報(bào)道多為個(gè)案報(bào)道或是小樣本研究,臨床表現(xiàn)不具備特異性,病理組織學(xué)上易誤診。有文獻(xiàn)[2-3]報(bào)道PMEC中存在表皮生長因子受
[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，
