Focal nodular hyperplasia's most recognizable gross feature is a central stellate scar seen in 60–70% of cases. Microscopically, a lobular proliferation of bland-appearing hepatocytes with a bile ductular proliferation and malformed vessels within the fibrous scar is the most common pattern.
Focal nodular hyperplasia (FNH) is the second most common benign tumor of the liver. [2] FNH is found in 0.2%– 0.3% of adults worldwide. [2] FNH is more common in females (10:1 female to male ratio) except in Japan and China, in which there is a more equal prevalence of cases between females and males. [2]
Nodular regenerative hyperplasia (NRH) is a rare liver disease, characterised by the growth of nodules within the liver, resulting in liver hyperplasia.While in many cases it is asymptomatic and thus goes undetected – or is only discovered incidentally while investigating some other medical condition – in some people it results in non-cirrhotic portal hypertension (NCPH).
Well-demarcated, nodular lesions ranging 2–5 mm in pulmonary parenchyma. Type II pneumocytes without nuclear atypia lined thickened alveolar septa and proliferated papillary structures. Enlarged cuboidal cells lining mildly thickened alveolar septa. [11] Enlarged cuboidal cells have abundant, eosinophilic cytoplasm and large, round nuclei. [12]
Multiphasic MRI is useful in diagnosing various types of liver lesions such as hepatocellular carcinoma, cholangiocarcinoma, hepatocellular adenoma, focal nodular hyperplasia, and hemangioma. [19] FibroTest (FibroSure in the USA) and FibroMax are non-invasive tests using a blood sample and an algorithm.
[3] [4] The significance of making a specific diagnosis is that, unlike other benign liver tumors such as hemangioma and focal nodular hyperplasia, hepatic adenomas have a small but meaningful risk of progressing into a malignancy. [3]
Hepatic adenomas may be misidentified as focal nodular hyperplasia in diagnostic imaging, though this condition is rare. However, hepatic adenomas in GSD I uniquely involve diffuse Mallory hyaline deposition, which is otherwise commonly observed in focal nodular hyperplasia. Unlike common hepatic adenomas related to oral contraception ...
Fibrolamellar carcinoma (FLC) is a rare form of carcinoma that typically affects young adults and is characterized, under the microscope, by laminated fibrous layers interspersed between the tumor cells. [1] It has been estimated that 200 new cases are diagnosed worldwide each year. [2]
