Coagulative Necrosis in Infarcts – What You Need to Know

“What is coagulative necrosis and how does it occur?”

Necrosis is defined as focal death along with the degradation of tissue by hydrolytic enzymes liberated by dead cells. It is invariably accompanied by an inflammatory reaction.

Type Of Necrosis

Morphologically, necrosis is classified into five distinct types:

Question 2. Write A Short Note On Coagulative Necrosis.
Answer:

It is characterized by the deposition of fibrin-like material, which has the staining properties of firing.

Examples of fibrinoid necrosis are immune complex vasculitis, autoimmune disease, and Arthus reaction.

Coagulative Necrosis Gross Appearance

• The focus of coagulative necrosis is pale, firm, and slightly swollen and is called an infarct.
• With progression, the affected area becomes yellowish, soft, and shrunken.

Coagulative Necrosis Microscopic Features

• Microscopically, the hallmark of coagulative necrosis is the conversion of normal cells into “tombstones,” i.e., outlines of cells are retained so that cell type can still be recognized, but their cytoplasmic and nuclear details are lost.
• Necrosed cells are swollen and have more eosinophilic cytoplasm than normal. Cells show nuclear changes such as pyknosis, karyorrhexis, and karyolysis.
• Necrosed focus is infiltrated by inflammatory cells, and dead cells are phagocytosed, leaving granular debris and fragments of cells.
