A hepatocellular adenoma is a relatively uncommon noncancerous liver tumor that may be mistaken for cancer. Rarely, it ruptures and bleeds or becomes cancerous.

Usually, these tumors cause no symptoms, so most remain undetected. Large adenomas may cause pain in the upper right part of the abdomen. Rarely, a hepatocellular adenoma suddenly ruptures and bleeds into the abdominal cavity, requiring emergency surgery. Very rarely, these tumors become cancerous.

Hepatocellular adenomas caused by oral contraceptive use may disappear when the woman stops taking the drug. If adenomas are large or located near the surface of the liver, surgery may be recommended because bleeding is a risk.
