Hepatocellular adenomas of the liver occur predominantly in women, usually during their thirties and forties. These are non-cancerous growths that occur in the liver. The majority of people who have developed this disorder have used oral contraceptive drugs. These tumors may become quite large and may be multiple within the liver. There is a small chance, about 10%, for these tumors to undergo a mutation and become malignant.
Causes of Hepatocellular Adenoma
The exact pathogenesis of these tumors is unknown. However, since they occur primarily in women, especially those taking oral contraceptives, a hormonal influence has been implicated. They have also been seen in congenital diseases, such as glycogen storage disease type 1.
Signs and Symptoms of Hepatocellular Adenoma
Pain in the right upper abdomen may occur. A lump or mass may be felt in the right upper abdomen.
