A 42-year-old woman with liver masses and long-term use of oral contraceptives.

摘要

A 42-year-old woman with a history of 25-year oral contraceptive use presented with abdominal pain and was found to have two exophytic liver masses. She had no known prior liver diseases, and her serum liver enzyme and AFP levels were normal. One of the masses was a hepatocellular adenoma and the other was a pigmented hepatocellular carcinoma. The exophytic appearance of both lesions was unusual. This case, once more, demonstrated the risk of hepatocellular adenomas to undergo malignant transformation. The reason for the brown pigment deposition in the hepatocellular carcinoma was not clear. The prognosis was expected to be excellent following complete surgical resection.
