Cirrhosis, whether caused by alcoholic hepatitis, viral hepatitis or other diseases, results in a disruption of the normal liver architecture, with bands of fibrosis separating nodules of regenerating hepatocytes. Some nodules can be larger and raise the suspicious of a malignancy, such as hepatocellular carcinoma. As a matter of fact, patients with cirrhosis are at increased risk for developing hepatocellular carcinoma. Patients with a focal lesion in the setting of cirrhosis are often biopsied with FNA, although accuracy may be higher with needle biopsy.

Cytologic diagnostic features

  • Normal-appearing hepatocytes, sometimes with steatosis
  • Focal atypia in some cases (marked variation in nuclear size, prominent nucleoli, binucleation)

Differential diagnosis

  • Hepatocellular carcinoma
  • Hepatic adenoma
  • Focal nodular hyperplasia
  • Normal liver
  • Nodular regenerative hyperplasia (nodular transformation of the liver)

When hepatocyte atypia is due to cirrhosis, smears show a spectrum ranging from normal to markedly atypical hepatocytes, whereas smears from a hepatocellular carcinoma are usually monomorphic. In hepatocellular carcinoma, other diagnostic features are an increased N/C ratio, a trabecular arrangement of hepatocytes surrounded by endothelial cells, and atypical naked nuclei. The different benign conditions are cytologically indistinguishable and the diagnosis rests on clinical-pathologic correlation.
