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 .
Liver tumors (also known as hepatic tumors) are abnormal growth of liver cells on or in the liver. Several distinct types of tumors can develop in the liver because the liver is made up of various cell types. [1] Liver tumors can be classified as benign (non-cancerous) or malignant (cancerous) growths.
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]
Hepatocellular carcinoma (HCC [1]) is the most common type of primary liver cancer in adults and is currently the most common cause of death in people with cirrhosis. [2] HCC is the third leading cause of cancer-related deaths worldwide. [3]
The quadrate lobe is an area of the liver situated on the undersurface of the medial segment left lobe (Couinaud segment IVb), bounded in front by the anterior margin of the liver, behind by the porta hepatis, on the right by the fossa for the gall-bladder, and on the left by the fossa for the umbilical vein.
A liver metastasis is a malignant tumor in the liver that has spread from another organ that is affected by cancer. The liver is a common site for metastatic disease because of its rich, dual blood supply (the liver receives blood via the hepatic artery and portal vein). Metastatic tumors in the liver are 20 times more common than primary liver ...
The right vertical limb of the "H" defines the left and right functional lobes, while the left vertical limb of the "H" defines the right and left anatomical lobes. The horizontal line between the vertical limbs of the "H" represents the porta hepatis. The quadrate and caudate lobe lie superior and inferior to this line respectively.
Councilman bodies are often named for the hepatocytes undergoing apoptosis, which occurs in the portal tracts and lobules of the liver. Inflammation of the liver is caused by the cytotoxic killing of hepatocytes, or Councilman bodies. Eventually, this inflammation leads to liver damage in viral hepatitis. [7]
