上皮细胞瘤

Results Pulmonary carcinosarcoma and blastoma both were found to be rare malignant tumors, and both epithelial and mesenchymal elements can be seen under the microscopy with different characteristic features.

结果 肺癌肉瘤及肺母细胞瘤均为肺内罕见的恶性肿瘤，镜下均可见上皮及间质两种成分，但又有其同之处，手术前很难确诊。

Results Of the 52 specimens, 38 were located in the ciliary body (73.1%), and 14 lesions involved the iris (26.9%). According to the results of histogenetic classification, the tumors of ciliary sensory epithelium were ranked the first place (20 cases, 38.5%) while malignant melanoma, the second one (14 cases, 26.9%) followed by melanocytoma (9 cases, 17.3%) and granulomatous lesions (5 cases, 9.6%).

结果 52例组织标本按解剖部位分类：位于睫状体病变38例（73.1%），原发于睫状体累及虹膜组织14例（26.9%）；按组织来源分类：占第1位者为睫状体神经上皮来源的肿瘤20例（38.5%），第2位者为恶性黑色素瘤14例（26.9%），第3和第4位者分别为黑色素细胞瘤9例（17.3%）和肉芽肿性炎性病变5例（9.6%）。

Result: CDK4 and P16 were expressed in parabasal layers and the upper layer, mainly in the prickle and granular layers of cholesteatoma epithelium.

结果：CDK4、P16均表达于胆脂瘤上皮的棘细胞层、颗粒层和角质层，阳性率分别为68.6%、88.6%，高于对照组(前者P=0.011，后者P=0.02)。

We used the avidin-biotin complex technique and EGFR monoclonal antibody to evaluate the expression of EGFR in 29 cases of cholesteatoma and 34 samples of normal postauricular skin. Of patients with cholesteatoma, 79%(23 cases) had EGFR-positive cells in the basal layer, 66%(19 cases) in the parabasal layer, and 62%(18 cases) in the upper layer of the epithelial tissue.

本研究利用免疫组织化学酵素抗体法（avidin-biotin-peroxidase complex，ABC method）以 EGFR 单株抗体免疫染色，评估29例胆脂瘤与34例耳廓后皮肤两者组织上皮内 EGFR 阳性细胞之分布表现。

Methods A case of Perivascular epithelioid cell tumor of uterine cervix was studied by microscopy and immunohistochemistry,with review of the relevant literature.

应用光镜观察及免疫组化染色对1例子宫颈血管周上皮样细胞瘤进行临床病理分析，同时复习相关文献。
