27例经病理证实胃癌(低分化腺癌和管状腺癌各8例,粘液腺癌7例,未分化癌2例、印戒细胞癌和乳头状腺癌各1例)和10例非瘤性胃粘膜在扫描电镜低倍率(500倍以下)和高倍率(5000倍以上)下观察,结合光镜诊断进行分型并加以讨论。结果:低倍所见,癌瘤表面粗糙,凹凸不平,正常结构全部消失。癌细胞排列紊乱,形成大小不等,不规则
Twenty-seven cases of gastric cancer confirmed by pathology (8 cases of poorly differentiated adenocarcinoma and 7 cases of tubular adenocarcinoma, 7 cases of mucinous adenocarcinoma, 2 cases of undifferentiated carcinoma, 1 case of signet ring cell carcinoma and 1 case of papillary adenocarcinoma) and 10 cases of non-neoplastic The gastric mucosa was observed under scanning electron microscopy (500-fold or less) and high-magnification (5000-fold or more) observations, combined with light microscopy for classification and discussion. Results: At low magnification, the tumor surface was rough, uneven, and the normal structure disappeared. The cancer cells are arranged in disorder, and they are of different sizes and irregularities.
