为探讨涎腺液表皮样癌的组织发生,本文采用三种特异性抗体:上皮肤抗原(EMA);肌动蛋白(actin);波形蛋白(vimentin)对25例涎腺粘液表皮样癌进行免疫组织化学研究。结果发现,粘液表皮样癌中三种肿瘤细胞对EMA反应阳性,部分表皮样细胞和中间细胞对actin和Vimentin反应阳性,粘液细胞反应阴性。研究结果表明,粘波表皮样癌是上皮源性的肿瘤,其中表皮样细胞和中间细胞具有肌上皮细胞的分化特征。提示,肿瘤性腺上皮与肿瘤性肌上皮细胞同时参与了该肿瘤的组织发生。 In order to explore the histopathology of salivary gland fluid epidermoid carcinoma, we used three kinds of specific antibodies: epithelial skin antigen (EMA), actin and vimentin to immunize 25 cases of mucoepidermoid carcinoma Histochemistry. The results showed that three kinds of tumor cells in mucoepidermoid carcinoma were positive to EMA, some epidermoid cells and intermediate cells reacted positively to actin and Vimentin, and mucous cell reaction was negative. The results show that epidermoid carcinoma of the sticky epithelium is epithelial tumor, in which epidermoid cells and intermediate cells have myoepithelial cell differentiation characteristics. Tip, tumor gonadal epithelial cells and tumor cells simultaneously involved in the tumor tissue.
