Most areas look like hyalinizing necrosis, the type not for malignancy. Only the first column, second photo has the left area looks like coagulative necrosis which is tumor necrosis. As discussed above, coagulative necrosis maintains cell contour but lose cellular detail (ghost cells): nuclei most time are dissolved and sometimes only nuclear dusts left, and cytoplasm has lost it's longitudinal fibrillation and become evenly pink.
The 2 photos on the fourth column show cells with karyorrhexis, which are cells in the process of death, not dead yet.
The last column shows viable tumor cells, don't appreciate necrosis yet.
abin译:
大部分区域看上去象玻璃样坏死,不是恶性的那种。仅第一排的第二张图片左侧,看似凝固性坏死,为肿瘤性坏死。如上讨论,凝固性坏死保留细胞轮廓但丢失细胞细节(鬼影细胞,or细胞残影):大多时候核溶解,有时仅剩核尘,胞浆失去纵向的原纤维,变成均匀红染。
第4排的两张照片显示细胞有核碎裂,是处于坏死过程中的细胞,还不是坏死。
最后一排显示不同的肿瘤细胞,还不能认为是坏死。
