Histological lesion of adenovirus viral hepatitis

Adenovirus is a type of virus that can cause hepatitis, which is inflammation of the liver. The histological lesions seen with adenovirus viral hepatitis include:
1. Hepatocellular degeneration: This is the most common histological finding in adenovirus hepatitis. The liver cells, or hepatocytes, show signs of damage and degeneration, which can lead to cell death.
2. Infiltration of inflammatory cells: The liver tissue shows presence of infiltrates of lymphocytes, plasma cells, and macrophages around the areas of cell degeneration. These inflammatory cells are responding to the virus and attempting to clear the infection.
3. Ballooning degeneration: Hepatocytes may become swollen and enlarged, known as ballooning degeneration. This is due to accumulation of fluid and cellular debris within the cells.
4. Councilman bodies: These are small, eosinophilic bodies found within the liver tissue. They are thought to represent hepatocyte apoptosis, or programmed cell death, as a result of viral infection.
5. Focal necrosis: Adenovirus hepatitis can cause areas of liver tissue necrosis (tissue death). These areas appear as pale, eosinophilic, or basophilic areas due to loss of cellular structure.
Overall, the histological lesions of adenovirus hepatitis are similar to those observed in other viral hepatitis infections including Hepatitis A, B and C. However, the lesions are less extensive and less severe compared to other viral hepatitis.
