| 6. | Here is the lipoma at high magnification . this is a good example of how a benign neoplasm mimics the tissue of origin
高倍镜下，从这个脂肪瘤很容易观察到良性瘤和起源组织的相似性。 |
| 7. | Here is the lipoma at high magnification . this is a good example of how a benign neoplasm mimics the tissue of origin
在低倍镜下，小肠脂肪瘤和黏膜界限很清，这个瘤分化良好，只表现为局限性肿块，很难和正常脂肪组织区分开。 |
| 8. | However , the overall difference between them is not great , so this benign neoplasm mimics the normal tissue quite w ell and this , therfore , is well - differentiated
但总的区别不是很大，因此良性肿瘤跟正常组织很相似，即分化好。 |
| 9. | However , the overall difference between them is not great , so this benign neoplasm mimics the normal tissue quite well and this , therefore , well - differentiated
然而它们之间的不同不是很大，因此这种良性肿瘤与正常的组织相似性较大，分化较好。 |
| 10. | Benign neoplasms can be multiple , as is shown in this uterus with leiomyomas of varying size , but all benign and well - circumscribed firm white masses
良性肿瘤可以是多样的,如图所示子宫平滑肌瘤样大小不等，但几乎所有的良性肿瘤都为边界清楚，坚实的白色肿物。 |
