恶性瘤

Objective : To investigate expression of oncogene and its significance in benign and malignant preomorphic adenomas of salivary gland.

采用免疫组织化学方法对5例瘤旁腺体，21例良性多形性腺瘤和24例恶性多形性腺瘤中C-H-ras和P53蛋白产物的表达进行形态学观察。

Methods MR Perfusion Weighted images was performed in 47 patients with meningiomas followed by conventional imaging.Results The mean rCBV values of angioblastic was the highest in the parenchyma of tumor.

对47例脑膜瘤病人行MR灌注成像检查，对5种亚型的良性脑膜瘤的MR灌注成像进行分析，并与非典型性及恶性脑膜瘤进行比较。

Results All the 7 cases were female, 2 cases were solitary fibrous tumor, 2 cases were myofibroblastoma, 1 case was inflammatory myofibroblastic tumour, 1 case was fibromatosis, and 1 case was low grade myofibroblastic sarcoma.

结果 7例患者均为女性，2例为孤立性纤维性肿瘤；2例为肌纤维母细胞瘤；1例为纤维瘤病；1例为炎性肌纤维母细胞瘤；1例为低度恶性肌纤维母细胞肉瘤。

The pathology of tumours included 8 cases of phechoromocytoma(1 case appears malignancy),4 cases of ganglioneuroma,4 cases of adrenal myelolipoma, 2 cases of melanoma,4 cases of other lesions. Current median follow up ,available on 19 patients,was 14 months(ranges 3 to 47),no local recurrence and metastases was observed.

术后病理报告：嗜铬细胞瘤8例其中1例恶性），髓样脂肪瘤4例，神经节细胞瘤4例，脂肪肉瘤2例，其它病变4例。3例失访，19例随访3～47个月，平均14±9个月，未见局部复发和转移。

The expression of Cat V was significantly raised in the epithelial-rich and mixed cell thymomas when compared with that in the lymphocyte-rich ones. No statistically significant difference was found on the variables such as perioperative myasthenic crisis, sex or age of patient, duraton of sickness and expression of Cat V.

上皮细胞型(75.00%)和混合细胞型(85.00%)胸腺瘤中Cat V阳性表达率显著高于淋巴细胞型(21.21%)(P.01)，而上皮细胞型与混合细胞型之间差异无统计学意义；良性与恶性胸腺瘤中Cat V阳性表达率差异无统计学意义；男性患者与女性患者之间、35岁以上患者与以下患者之间胸腺瘤中Cat V阳性表达率差异均无统计学意义。

Objective:To study the diagnostic and differential criteria for benign and malignant osteoblastoma.

骨母细胞瘤临床病理学研究李亦民丁彦青徐莉摘要探讨良性骨母细胞瘤和恶性骨母细胞瘤的诊断和鉴别诊断标准。

In contrast to plexiform neurofibromas, plexiform schwannoma is only weakly associated with neurofibromatosis type 1 (von Recklinghausen's disease), and has little malignant potential.

相对於丛状神经纤维瘤，丛状神经鞘瘤与第一型予纤维瘤病(neurofibromatosis type 1，von Recklinghausen's disease)的相关很薄弱，而且没有恶性变化的倾向。

Malignant meningioma or rhabdoid meningioma may have similar histopathology, but the immunohistochemical staining pattern shown is not consistent with any antibody commonly used for meningioma.

恶性脑膜瘤或横纹肌样脑膜瘤也可能出现相似的组织病理学改变，但该例显示的免疫组化染色模式不同于任何一种常用于脑膜瘤诊断的抗体。

RM has special morphological characteristics; it should be differentiated from gemis tocytic astrocytoma, atypical teratoid/rhabdoid tumor, and malignant melanocytoma.

RM有特殊的组织学特点，应注意与胖细胞型星形细胞瘤、非典型畸胎样瘤/横纹肌样瘤、恶性黑色素瘤等鉴别。

The biological behavior of thymoma with or without capsule might not be assessment standard for benign or malignancy.

有包膜的胸腺瘤和无包膜的胸腺瘤的生物学行为不是判断胸腺瘤良恶性的最佳指标。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
