Diagnosis of well-differentiated hepatocellular lesions:

نویسنده

  • Sanjay Kakar
چکیده

The most common problems encountered in the differential diagnosis of hepatocellular lesions are: (a) adenoma vs well-differentiated hepatocellular carcinoma (HCC) in non-cirrhotic liver, (b) focal nodular hyperplasia (FNH) vs adenoma in non-cirrhotic liver, and (c) HCC vs high grade dysplastic nodules and other non-neoplastic nodules in cirrhotic liver. This discussion provides an update of immunohistochemistry and other techniques that aid in this differential diagnosis.

Benign hepatocellular nodules of healthy liver: focal nodular hyperplasia and hepatocellular adenoma

Owing to the progress of imaging techniques, benign hepatocellular nodules are increasingly discovered in the clinical practice. This group of lesions mostly arises in the context of a putatively normal healthy liver and includes either pseudotumoral and tumoral nodules. Focal nodular hyperplasia and hepatocellular adenoma are prototypical examples of these two categories of nodules. In this re...

Fine needle aspiration biopsy of the liver: Algorithmic approach and current issues in the diagnosis of hepatocellular carcinoma

The role of fine needle aspiration biopsy (FNAB) in the evaluation of focal liver lesions has evolved. Guided FNAB is still useful to procure a tissue diagnosis if clinical, biochemical and radiologic findings are inconclusive. Major diagnostic issues include: (i) Distinction of benign hepatocellular nodular lesions from reactive hepatocytes, (ii) Distinction of well-differentiated hepatocellul...

Testosterone-receptor positive hepatocellular carcinoma in a 29-year old bodybuilder with a history of anabolic androgenic steroid abuse: a case report

BACKGROUND Continuous use of anabolic androgenic steroid in high-doses is associated with substantial health risks, including hepatocellular adenoma. Malignant transformation from hepatocellular adenoma to hepatocellular carcinoma after anabolic androgenic steroid abuse has been rarely reported. The morphological distinction of adenoma from well-differentiated hepatocellular carcinoma is challe...

Liver precancerous lesions and hepatocellular carcinoma: the histology report.

The current ability to increase the survival of patients with hepatocellular carcinoma (HCC) relies upon the surveillance of cirrhotic patients. Surveillance allows HCC precursors (dysplastic nodules) and malignant tumors to be recognized at an earlier stage making cure possible. Radiology plays a major role in HCC diagnosis because HCC is characterized by neoarterial vascularisation with a typ...

Lack of Mutation in the Hot Spot Region of the Human P53 Gene in a Number of Iranian Hepatocellular Carcinoma Patients

  Objectives and Background: Mutation directed inactivation of the tumor suppressor gene p53 have been found incountries with high frequency for hepatocellular carcinomas (HCCs). Our goal in the present study was screening of the p53 gene in tumor tissues from HCC affected individuals in southwest Iran for putative mutations in exons 7 and 8 that are known as hot spot regions. Materials & Met...
