高倍镜下，脉管炎患者动脉壁坏死，可见嗜中性粒细胞核碎片(核碎裂)。

At higher magnification, vasculitis with arterial wall necrosis is seen. Note the fragmented remains of neutrophilic nuclei (karyorrhexis).

许多细胞核发生了核浓缩，接着出现核碎裂和核溶解现象。

Many nuclei have become pyknotic (shrunken and dark) and have then undergone karorrhexis (fragmentation) and karyolysis (dissolution). The cytoplasm and cell borders are not recognizable.
