Which of the following is not a coagulative necrosis-
**Core Concept**
Coagulative necrosis is a type of accidental cell death that occurs due to ischemia or infarction, characterized by the preservation of cell outlines and architecture. It is commonly seen in solid organs such as the heart, liver, and kidney.
**Why the Correct Answer is Right**
Coagulative necrosis typically occurs in tissues with a rich blood supply, where the cells are subjected to a sudden loss of oxygen and nutrients. This type of necrosis is often seen in the setting of a myocardial infarction or a hepatic infarction, where the cells undergo a process of cell death without significant inflammation. The preserved cell outlines are due to the denaturation of proteins in the cell, which leads to a coagulation-like appearance.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because coagulative necrosis is a common type of cell death in the setting of an infarct, such as a myocardial infarction.
**Option B:** This option is incorrect because coagulative necrosis is typically seen in solid organs, such as the liver and kidney, which have a rich blood supply.
**Option C:** This option is incorrect because coagulative necrosis is often associated with a lack of inflammation, whereas liquefactive necrosis is typically seen in tissues with a high water content and is associated with significant inflammation.
**Clinical Pearl / High-Yield Fact**
It's worth noting that coagulative necrosis is a reversible process in the early stages, and prompt reperfusion or revascularization can prevent permanent cell death. This is in contrast to liquefactive necrosis, which is often irreversible.
**Correct Answer: C. Liquefactive necrosis**
