Show Hint
Necrosis Patterns:
Liquefactive Necrosis $\rightarrow$ Abscesses (pyogenic pus) & Brain infarcts.
Coagulative Necrosis $\rightarrow$ Ischemic necrosis in solid organs.
Caseous Necrosis $\rightarrow$ Tuberculosis.
Liquefactive Necrosis $\rightarrow$ Abscesses (pyogenic pus) & Brain infarcts.
Coagulative Necrosis $\rightarrow$ Ischemic necrosis in solid organs.
Caseous Necrosis $\rightarrow$ Tuberculosis.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Pyogenic bacterial infections trigger massive neutrophil infiltration and release of lysosomal myeloperoxidases that digest necrotic tissue into liquid pus.
Step 2: Detailed Explanation:
Pathological types of necrosis:
1. Liquefactive (Colliquative) Necrosis: Characterized by rapid, complete enzymatic digestion of dead cells into a liquid viscous mass (pus/purulent exudate). It is the characteristic hallmark of acute pyogenic bacterial abscesses (due to lysosomal enzymes released by dying neutrophils/macrophages) and ischemic hypoxic brain infarctions.
2. Coagulative Necrosis: Architecture preserved (infarcts of heart, kidney).
3. Caseous Necrosis: 'Cheesy' architecture (Tuberculosis).
4. Fat Necrosis: Enzymatic saponification of adipose tissue (Pancreatitis).
Step 3: Final Answer:
Hence, Liquefactive necrosis is noticed in an abscess, matching option (B).
