大量细胞死亡即为坏死。坏死的类型取决于损伤的性质、组织的类型和持续的时间长短。图为凝固性坏死。是由缺血引起的典型坏死类型。图示：肾脏肾皮质区的楔型苍白区域即为凝固性坏死（梗死）。
When many cells undergo necrosis at once, then definable patterns of necrosis are produced, depending upon the nature of the injury, the type of tissue, and the length of time. This is an example of coagulative necrosis. This is the typical pattern with ischemia and infarction (loss of blood supply and resultant tissue anoxia). Here, there is a wedge-shaped pale area of coagulative necrosis (infarction) in the renal cortex of the kidney.
