Ans a Young age

This tumor generally occurs in younger patients without a history of cirrhosis.

Well demarcated and encapsulated and may have a central fibrotic scar

Good prognosis than HCC, probably related to high resectability rates, lack of chronic liver disease, and a more indolent course. Long-term survival can be expected in approximately 50% to 75%

Lymph nodes can be involved and associated with poor outcome
