Liver tumors can be classified as benign (non-cancerous) or malignant (cancerous) growths. They may be discovered on medical imaging (even for a different reason than the cancer itself), and the diagnosis is often confirmed with liver biopsy. [2] Signs and symptoms of liver masses vary from being asymptomatic to patients presenting with an ...
Liver tumor types by relative incidence in adults in the United States, with focal nodular hyperplasia at right. [ 3 ] Focal nodular hyperplasia's most recognizable gross feature is a central stellate scar seen in 60–70% of cases.
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 ...
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.
Liver cancer is fairly rare, but since 1990, its rate has doubled, rising from 3.5 to 6.5 per 100,000, says Otis Brawley, MD, former chief medical officer for the American Cancer Society. Liver ...
Certain benign liver tumors, such as hepatocellular adenoma, may sometimes be associated with coexisting malignant HCC. Evidence is limited for the true incidence of malignancy associated with benign adenomas; however, the size of hepatic adenoma is considered to correspond to risk of malignancy and so larger tumors may be surgically removed.
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.
Suspicion of hepatomegaly indicates a thorough medical history and physical examination, wherein the latter typically includes an increased liver span. [citation needed] On abdominal ultrasonography, the liver can be measured by the maximum dimension on a sagittal plane view through the midclavicular line, which is normally up to 18 cm in ...
