However , about 25 % of cases exhibit frank malignant features of prominent nuclear pleomorphism ( as in this case ) , mitotic activity or necrosis 然而,大约25 %的病例显示恶性特征诸如明显核多型现象(比如此例) 、核分裂活性或者坏死。
Based on poor glandular formation , necrosis , cellular atypia , nuclear pleomorphism , invasion of soft tissue and bone , and vascular permeation 主要基于腺管的结构分化不良,坏死,细胞异型性,核多型性,软组织和骨浸润以及血管浸润。
This astrocytoma demonstrates increased cellularity and pleomorphism , as compared to normal brain . note the very pleomorphic cell in the center 与正常大脑相比,星形细胞瘤显示出细胞内容丰富并有明显多形性。注意中心部位的多形性细胞。
At high magnification , the characteristic " indian file " strands of infiltrating lobular carcinoma cells are seen in the fibrous stroma . pleomorphism is not great 高倍在纤维间质中可见浸润性小叶癌癌细胞单行排列的特征性病变。多形性不大。
Microscopically , the adrenal cortical adenoma at the right resembles normal adrenal fasciculata . the capsule is at the left . there may be some cellular pleomorphism 显微镜下,右侧的肾上腺皮质腺瘤类似正常的肾上腺束状带,左边为包膜。肿瘤细胞具有一定的异型性。
Both benign and malignant endocrine neoplasms demonstrate some degree of cellular pleomorphism , so it is not easy to tell benign from malignant on histologic grounds alone 无论是良性内分泌肿瘤还是恶性内分泌肿瘤都显示一定程度的细胞异型性,因此仅从组织学上很难区分肿瘤的良恶性。
The neoplastic epithelial cells within the duct show minimal hyperchromatism and pleomorphism , but they have holes with sharp margins as though punched out by a cookie cutter 导管内的肿瘤上皮细胞显示出轻微的着色过深与多形性,但它们的空洞边缘锐利就好象是用小甜点切割刀切成的一样。
