本文用常规光镜检查和免疫组织化学方法研究了12例老年患者的麦克尔细胞癌,并对有关组织发生进行了讨论。材料和方法:本组12例年龄在54～89岁(平均73.4岁),其中男性3例,女性9例。肿瘤多位于面部和下肢。活检标本从原发瘤和复发瘤获取,用Bouin液固定,按常规光镜要求处理,其中3例用冰冻材料。石腊切片用HE染色和Grimelius嗜银染色法。采用过氧化酶—抗过氧化酶技术,用抗S-100蛋白神经元—特异性烯醇酶、蛋内啡肽(met-enk-
In this paper, 12 cases of elderly patients with Michael’s cell carcinoma were studied by routine light microscopy and immunohistochemical methods, and related histogenesis was discussed. Materials and Methods: The 12 patients aged 54 to 89 years old (average 73.4 years old) included 3 males and 9 females. The tumors are mostly on the face and lower limbs. Biopsy specimens were obtained from primary tumors and recurrent tumors, fixed with Bouin fluid and treated with conventional light microscopy, of which 3 were frozen material. Paraffin sections were stained with HE and Grimelius silver staining. Using peroxidase-antiperoxidase technology, using anti-S-100 protein neuron-specific enolase, endorphins (met-enk-
