This entity mainly needs to be distinguished from Hepatocellular carcinoma.
Hepatocellular adenoma versus carcinoma
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.
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.
- Portal triads, which commonly persist in well-differentiated hepatocellular carcinomas.
