Liver transplantation is a potential treatment for acute or chronic conditions which cause irreversible and severe ("end-stage") liver dysfunction. [4] Since the procedure carries relatively high risks, is resource-intensive, and requires major life modifications after surgery, it is reserved for dire circumstances.
Even though many COVID-19 patients recover within 2–6 weeks of the onset of symptoms, some develop symptoms that come and go for months. The possibility has been raised, but needs to be investigated further, that patients with long COVID-19 may be predisposed to the development of lung cancer.
Piecemeal necrosis in liver aka interface hepatitis is necrosis of the limiting plates, by inflammatory cells. It may be identified as actual necrosis of cells or by irregularity of the limiting plates which is caused IOS's hepatocytes and replacement with inflammatory cells and/or fibrosis.
Surgical resection is associated with a greater than 60% survival rate at 5 years and a recurrence rate greater than 70%. [6] Surgical removal of the tumor is associated with better cancer prognosis, but only 5–15% of patients are suitable for surgical resection due to the extent of disease or poor liver function.

Liver regeneration is the process by which the liver is able to replace damaged or lost liver tissue. The liver is the only visceral organ with the capacity to regenerate. [1] [2] The liver can regenerate after partial hepatectomy or injury due to hepatotoxic agents such as certain medications, toxins, or chemicals. [3]
Histopathology of a ballooning hepatocyte.png, H&E stain. Ballooning degeneration centre-left and centre-right. H&E stain. A Councilman body can also be seen in the upper-right of the section. In histo pathology, ballooning degeneration, formally ballooning degeneration of hepatocytes, is a form of liver parenchymal cell (i.e. hepatocyte) death.
The most frequent liver cancer, accounting for approximately 75% of all primary liver cancers, is hepatocellular carcinoma (HCC). [15] HCC is a cancer formed by liver cells, known as hepatocytes, that become malignant. In terms of cancer deaths, worldwide HCC is considered the 3rd most common cause of cancer mortalities. [16]
In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue, consisting of portal triads, hepatocytes arranged in linear cords between a capillary network, and a central vein.
