**Question:** Finding on histopathological examination in liver in case of malaria is -
A. Hepatocellular necrosis
B. Liver cirrhosis
C. Portal inflammation
D. Hepatocellular hyperplasia
**Correct Answer: A. Hepatocellular necrosis**
**Core Concept:** Malaria is a parasitic infection caused by Plasmodium species, primarily affecting the liver, lungs, and red blood cells. The liver plays a crucial role in clearing the parasite and producing anti-parasitic response.
**Why the Correct Answer is Right:** Hepatocellular necrosis occurs when the liver cells are damaged or destroyed due to the direct cytoadherence of Plasmodium parasites and reactive oxygen species (ROS) production within the liver cells. This leads to inflammation and fibrosis in the liver, which can further exacerbate liver dysfunction.
**Why Each Wrong Option is Incorrect:**
**A. Liver cirrhosis**: This is a chronic liver disease characterized by fibrosis and nodule formation. While malaria can cause liver fibrosis, the finding of liver cirrhosis on histopathology would be an overgeneralization and not specific to malaria.
**B. Liver cirrhosis**: Similar to option A, cirrhosis is a result of long-standing inflammation and fibrosis. It is not specific to malaria and would not be the correct finding on histopathology in malaria.
**C. Portal inflammation**: Portal inflammation is a general term for inflammation in the portal triad (portal vein, bile duct, and hepatocytes). While malaria can cause inflammation, it is not specific to malaria and would not be the most consistent finding on histopathology.
**D. Hepatocellular hyperplasia**: This refers to the increased production of liver cells (hepatocytes) due to damage or inflammation. While malaria can cause hepatocellular hyperplasia as a compensatory response, it is not specific to malaria and would not be the most consistent finding on histopathology.
**Clinical Pearl:** Understanding the histopathological findings in malaria can help differentiate it from other liver diseases and provide valuable information for diagnosis and prognosis. A combination of hepatocellular necrosis, portal inflammation, and fibrosis is more characteristic of malaria-induced liver damage.
