Necrosis with cell bodies retained as ghost cells are –
## Core Concept
The question pertains to the histopathological features of cell death, specifically necrosis. Necrosis is a form of cell death that results from acute cellular injury or severe damage. The type of necrosis described, where cell bodies are retained as "ghost cells," indicates a specific pattern of cell death.
## Why the Correct Answer is Right
The correct answer, coagulative necrosis, is characterized by the preservation of the cell's outline, often referred to as "ghost cells." This type of necrosis typically occurs in tissues with a framework of supporting connective tissue, such as the heart, liver, and kidneys. The process involves the denaturation of proteins within the cell, leading to a glassy, eosinophilic appearance under the microscope, while the cell's shape is maintained. This matches the description provided in the question.
## Why Each Wrong Option is Incorrect
- **Option A:** Liquefactive necrosis involves the digestion of dead cells, resulting in a liquid or soft mass. This does not match the description of cell bodies being retained as ghost cells.
- **Option B:** Fibrinoid necrosis is often seen in immune-mediated vascular injuries and does not specifically describe the retention of ghost cells.
- **Option C:** Caseous necrosis is characteristic of tuberculosis, where the necrotic tissue resembles cottage cheese. It does not feature ghost cells.
## Clinical Pearl / High-Yield Fact
A key point to remember is that coagulative necrosis, which results in ghost cells, is commonly seen in hypoxic/ischemic injuries in solid organs like the heart and kidneys. This pattern of necrosis is a hallmark of myocardial infarctions (heart attacks) and acute tubular necrosis in the kidneys.
## Correct Answer: C. Coagulative necrosis
