腺瘤性息肉与正常粘膜上皮比较(高倍镜)

腺瘤性息肉与正常粘膜上皮比较(高倍镜)

高倍镜:左侧为正常的结肠粘膜上皮,与之相比右侧为腺瘤性息肉的非典型增生上皮。腺瘤性息肉与正常粘膜上皮细胞相比细胞核染色加深、大小不一。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。

At high magnification, the normal colonic epithelium at the left contrasts with the atypical epithelium of the adenomatous polyp at the right. Nuclei are darker and more irregularly sized and closer together in the adenomatous polyp than in the normal mucosa. However, the overall difference between them is not great, so this benign neoplasm mimics the normal tissue quite well and this, therefore, well-differentiated.
