结肠腺瘤性息肉(低倍镜)


小腺瘤息肉(管状腺瘤)带有小蒂,镜下可见它比正常的结肠黏膜有更多的拥挤的无组织的腺体。杯状细胞减少,沿着息肉的腺体细胞有着色过深的细胞核。然而,它仍然是分化良好的和较局限的,蒂没有被破坏,是良性的。
This small adenomatous polyp (tubular adenoma) on a small stalk is seen microscopically to have more crowded, disorganized glands than the normal underlying colonic mucosa. Goblet cells are less numerous and the cells lining the glands of the polyp have hyperchromatic nuclei. However, it is still well-differentiated and circumscribed, without invasion of the stalk, and is benign.
