With EM, LM and histochemical method, 9 cases of signet-ring cell carcinoma of the stomach were studied to find out that most signet-ring cells resulted from accumulation of numerous mucus-secreting granules, and a few were caused by the formation of microcyst in the cytoplasm. 应用电镜、光镜及免疫组化法对9例胃印戒细胞癌进行研究,发现大部分印戒细胞癌是由胞质内大量粘液颗粒积聚所致,少数则由胞质内微囊形成所致。
The cystic areas often had haemorrhage and necrosis; besides all of the above characteristics, one case showed lots of signet-ring cells with AB/ PAS, CEA and S-100 protein negative. 其中1例除上述特征外还出现了大量的印戒细胞样瘤细胞,这些瘤细胞AB/PAS染色阴性,CEA阴性,S-100蛋白阴性,随访至今已4年余,无复发及转移。
Compared with primary carcinoma, metastatic carcinoma usually presented higher grade of differentiation and bigger signet-ring cells which were important in differential diagnosis. 组织学分化程度,转移癌比原发癌多明显提高,尤其印戒状癌细胞的体积常特大,更有意义。
An Ultrastructural Study on the Signet-Ring Cells of Gastic Carcinoma 胃印戒细胞癌的超微结构研究
The mucinous signet-ring cancer cells in high differentiation small cell adenocarcinoma should be differential diagnosis from mesothelium signet-ringoid change. 对高分化小细胞性腺癌中粘液性印戒细胞癌应与间皮细胞增生时印戒样变鉴别诊断;
There was some relationship between percentage of signet-ring cells and prognosis. 印戒细胞成分的多少与病人预后有关系。
