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.

Tumors of the Bile Ducts and Gallbladder
Both cancerous and noncancerous tumors of the bile duct or gallbladder are rare. When cancerous, these tumors are almost always fatal. The exception is a cancerous tumor of the gallbladder that is discovered accidentally, such as during gallstone removal surgery. If discovered in this way, the tumor may have been caught early enough to be removed completely, possibly producing a cure. When cancer of the gallbladder is diagnosed, there is almost always a co-existing medical condition found at the same time. Which of the following is the most likely associated medical condition?
