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.
Liver tumor types by relative incidence in adults in the United States (liver cancers in dark red color). [14] 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 ...
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. [58] Surgery is only considered if the entire tumor can be safely removed while preserving sufficient functional liver to maintain normal physiology.
Benign liver tumors generally develop on normal or fatty liver, are single or multiple (generally paucilocular), have distinct delineation, with increased echogenity (hemangiomas, benign focal nodular hyperplasia) or absent, with posterior acoustic enhancement effect (cysts), have distinct delineation (hydatid cyst), lack of vascularization or show a characteristic circulatory pattern ...
In histo pathology, ballooning degeneration, formally ballooning degeneration of hepatocytes, is a form of liver parenchymal cell (i.e. hepatocyte) death. The name is derived from the fact that the cells undergoing this form of cell death increase in size ( balloon ).
Treatment of hepatomegaly varies with the cause, so accurate diagnosis is the first concern. In auto-immune liver disease, prednisone and azathioprine may be used for treatment. [3] In lymphoma the treatment options include single-agent (or multi-agent) chemotherapy and regional radiotherapy, and surgery is an option in specific situations.
Congestive hepatopathy, is liver dysfunction due to venous congestion, usually due to congestive heart failure. The gross pathological appearance of a liver affected by chronic passive congestion is "speckled" like a grated nutmeg kernel; the dark spots represent the dilated and congested hepatic venules and small hepatic veins. The paler areas ...
Apoptosis of the liver of a mouse. Hepatocytes are the liver's primary parenchymal cells, forming 80% of the liver's mass and 60% of its cells. They are round in shape and contain a nucleus and organelles that contribute to metabolic and secretory functions. [5] Hepatocytes also play a pivotal role in liver inflammation. [6]
