结论恶性肌上皮瘤是一种上皮性肿瘤，其亚型透明细胞型恶性程度较高。
Conclusions The malignant myoepithelioma was epithelial tumour. The malignant grade of clear cell type was higher.
在透明细胞脑膜瘤中肿瘤细胞的核一般位于中心，而不是像这例中的核偏位。
Nuclei of neoplastic cells in clear cell meningiomas are centrally located, not eccentric like in this case.
目的研究环氧化酶-2（COX-2）在人肾透明细胞癌组织中的表达，分析其表达水平与肿瘤分期的关系。
Objective To study the expression of cyclooxygenase-2 (COX-2) in renal clear cell carcinoma tissues and its relation with the clinical tumor stage.
结果根据肿瘤性肌上皮细胞形态特征将其分为上皮细胞型、梭形细胞型、透明细胞型和类浆细胞型。
Results Neoplastic myoepithelial cells could be divided into epithelial, spindle, clear and plasmacytoid (hyaline) types according to their morphological characteristics.
方法观察12例病理诊断为软组织透明细胞肉瘤患者的临床特性，从肿瘤细胞的细胞质、细胞核及通过免疫组化染色进行分析。
Methods 12 cases, pathologically diagnosed as clear cell sarcoma of soft tissue, were observed from the morphological, immunohistochemical, and clinical Angle.
需要进一步临床随访，来确定与传统透明细胞肾细胞癌相比这些肿瘤是否更为惰性。
Further clinical follow-up is needed to determine whether these tumors are more indolent compared with the conventional clear cell renal cell carcinoma.
结论：国人非遗传性肾透明细胞癌中存在VHL基因的突变，且与患者年龄，肿瘤分期、分级无相关性。
The mutations of VHL gene were irrespective of the age and pathological grade and stage of patients.
其结果大多数癌除肝细胞肝癌、肾透明细胞癌外，大部分肿瘤细胞显示中等度到强阳性。在滑膜肉瘤、恶性间皮瘤及胸腺瘤上皮样成份弱阳性。
The majority of the carcinomas, except hepatocellular, adrenocortical clear cell ones are stained of strong or moderate intensity in the majority of tumor cells.
结论：肾透明细胞癌NOTCH1和JAG1表达均高于正常肾组织，且与肿瘤分级、分期及肿瘤大小有关。
Conclusions: The expression levels of NOTCH1 and JAG1 were higher in clear cell renal cell carcinoma than in normal kidney tissues and correlated with patients' clinical and pathological variables.
结论：肾透明细胞癌NOTCH1和JAG1表达均高于正常肾组织，且与肿瘤分级、分期及肿瘤大小有关。
Conclusions: The expression levels of NOTCH1 and JAG1 were higher in clear cell renal cell carcinoma than in normal kidney tissues and correlated with patients' clinical and pathological variables.
