Micrograph showing a Mallory body with the characteristic twisted-rope appearance (centre of image - within a ballooning hepatocyte). H&E stain. In histopathology, a Mallory body, Mallory–Denk body (MDB), or Mallory's hyaline is an inclusion found in the cytoplasm of liver cells. [1] Mallory bodies are damaged intermediate filaments within ...
These cells are particularly attracted to hepatocytes with Mallory bodies. [6] If chronic liver disease is also present: Fibrosis; Cirrhosis – a progressive and permanent type of fibrotic degeneration of liver tissue. Pathogenesis alcoholic liver injury Alcohol related liver disease
Histologic features include Mallory bodies, giant mitochondria, hepatocyte necrosis, and neutrophil infiltration in the area around the veins. Mallory bodies, which are also present in other liver diseases, are condensations of cytokeratin components in the hepatocyte cytoplasm and do not contribute to liver injury.
Microscopically, changes that can be seen include steatosis with large and swollen hepatocytes , evidence of cellular injury and cell death (apoptosis, necrosis), evidence of inflammation in particular in zone 3 of the liver, variable degrees of fibrosis and Mallory bodies. [65] [68] [69]
In the adult liver, most of the cells are binucleated, and most of the hepatocytes are tetraploid, which means that they have four times the amount of normal DNA. Their average lifespan is from approximately five months, and hepatocytes have a significant regeneration capacity after parenchymal loss by toxic processes, diseases or surgeries.
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.
Hepatocyte nuclei are round with dispersed chromatin and prominent nucleoli. Anisokaryosis (or variation in the size of the nuclei) is common and often reflects tetraploidy and other degrees of polyploidy, a normal feature of 30-40% of hepatocytes in the adult human liver. [4] Binucleate cells are also common. [citation needed]
The proportion of AST to ALT in hepatocytes is about 2.5:1, but because AST is removed from serum by the liver sinusoidal cells twice as quickly (serum half-life t 1/2 = 18 hr) compared to ALT (t 1/2 = 36 hr), so the resulting serum levels of AST and ALT are about equal in healthy individuals, resulting in a normal AST/ALT ratio around 1.
