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.
About 25–50% of hepatic adenomas cause pain in the right upper quadrant or epigastric region of the abdomen. [2] Since hepatic adenomas can be large (8–15 cm), patients may notice a palpable mass. However, hepatic adenomas are usually asymptomatic, and may be discovered incidentally on imaging ordered for some unrelated reason. [2] Large ...
A cavernous liver hemangioma or hepatic hemangioma is a benign tumor of the liver composed of large vascular spaces lined by monolayer hepatic endothelial cells. It is the most common benign liver tumour, and is usually asymptomatic and diagnosed incidentally on radiological imaging or during laparotomy for other intra-abdominal issues.
However, a benign tumor is not benign in the usual sense; the name merely specifies that it is not "malignant", i.e. cancerous. While benign tumors usually do not pose a serious health risk, they can be harmful or fatal. [2] Many types of benign tumors have the potential to become cancerous through a process known as tumor progression. For this ...
Higher rates of liver cancer occur where hepatitis B and C are common, including Asia and sub-Saharan Africa. [3] Males are more often affected with hepatocellular carcinoma (HCC) than females. [3] Diagnosis is most frequent among those 55 to 65 years old. [2] The leading cause of liver cancer is cirrhosis due to hepatitis B, hepatitis C, or ...
The lower left abdomen pain in this case can initially be described as a mild discomfort and is typically first connected with constipation. But after 24-48 hours, it may become more severe, sharp ...
It is the most common liver tumor with a prevalence of 0.4 – 7.4%. It is generally asymptomatic but also can be associated with pain complaints or cytopenia and/or anemia when it is very bulky. It is unique or paucilocular. It can be associated with other types of benign liver tumors.
Symptoms include vague abdominal pain, nausea, abdominal fullness, malaise and weight loss. They may also include a palpable liver mass. [14] Other presentations include jaundice, ascites, fulminant liver failure, encephalopathy, gynecomastia (males only), thrombophlebitis of the lower limbs, recurrent deep vein thrombosis, anemia and hypoglycemia.
