摘要
对150例手术切除的肺癌结合光镜观察,进行了超微结构分类,结果如下:Ⅰ.来自支气管表面上皮及其腺体的癌:包括鳞状细胞癌、腺癌、腺鳞癌,其中有些伴神经内分泌分化;此外,还有实性粘液细胞癌和腺样囊性癌。Ⅱ.来自细支气管及肺泡上皮的细支气管肺泡癌:再分为Clara细胞型、Ⅱ型肺泡细胞型、粘液细胞型及混合型。Ⅲ.来自神经内分泌细胞的癌:包括类癌、不典型类癌及小细胞癌,其中有些伴有鳞状上皮分化。对肺癌的组织学分类及超微结构分类进行了比较,并就其存在的问题进行了讨论,认为从超微结构水平对肺癌予以分类是必要的。
For purpose of providing more accurate histological typing of lung carcinoma, it is necessary to classify carcinoma of lung by electron microscopy. 150 cases of resected lung carcinoma were examined under electron microscopy. The results of ultrastructural typing of lung carcinoma were as follows: Ⅰ. Carcinomas derived from bronchial surface epithelium and its gland, including squamous cell carcinoma (28 cases), adenocarcinoma (35 cases), adenosquamous carcinoma (29 cases). Among them, some cases associated with neuroendocrine differentiation. In addition, solid mucinous cell Carcinoma (4 cases) and adenoid cystic carcinoma (2 cases) were seen. Ⅱ. Bronchiolo-alveolar Carcinomas (21 cases) derived froma Clara cell and type Ⅱ Pneumocyte, subdividing into clara cell (9 cases), type Ⅱ pneumocyte (3 cases), mucinous cell (5 cases) and mixed type (4 cases). Ⅲ. Carcinomas derived from neuroendocrine cell (Kulchitsky cell), including well differentiated (carcinoid. 13 cases), intermediate differentiated (atypical carcinoid, 12 cases), and poorly differentiated (small cell carcinoma, 6 cases). Among them, some cases associated with squamous differentiation. The ultrastructural classification was compared with histological clossification of lung carcinomas and the differences between them were discussed.
