Hepatocellular adenoma versus carcinoma

Histopathology of inflammatory hepatocellular adenoma, with inflammatory cells and minor atypia.[1]

A hepatocellular adenoma, in contrast to a carcinoma, has a well-defined border between the lesion and background liver, and is composed of hepatocytes with less significant cytologic atypia.[2]

Both hepatocellular adenoma and well-differentiated hepatocellular carcinoma may display:

  • Steatosis: A steatotic hepatocellular carcinoma is a common variant, found most commonly in small, well-differentiated tumors.[3]
  • Portal triads, which commonly persist in well-differentiated hepatocellular carcinomas.[4]
