In this case report, it is emphasized that duration of exposure to an oral contraceptive is not of prime importance. The patient was a 30-year-old woman complaining of sudden onset of severe epigastric pain which radiated to the right upper abdomen and the right shoulder. She had been using anovulatory pills for 18 months. A mass was felt in the right upper abdomen. The white cell count was 21,000/cu mm. Acute cholecystitis was the original diagnosis. In the next 4 days the bilirubin rose to 2.9 mg% and the alkaline phosphatase to 23.1 KA units. At laparotomy the gallbladder was found to be normal. Hepatomegaly was noted. A liver biopsy was taken. Subsequently a liver scan showed a large defect in the right lobe of the liver. Selective angiography of the right hepatic artery showed a large vascular mass. The diagnosis was changed to hepatic adenoma with secondary hemorrhage. Before further surgery the patient suffered a cardiorespiratory arrest and died. At autopsy a hepatic adenoma was found in the right lobe. A large embolus was found blocking the pulmonary arteries. The embolus was considered the cause of the sudden death.

The case of a liver tumor of 10 cm diameter in a 32-year-old asymptomatic woman is described with markedly elevated liver enzymes in the serum (transaminases and alkaline phosphatase). The tumor corresponded to a focal nodular hyperplasia or a hepatic adenoma. The regression of this hepatic tumor over a time period of 18 months after discontinuation of oral contraceptives was observed as well as a complete normalisation of laboratory findings. It is concluded that conservative management after withdrawal of hormonal contraception my be the preferable treatment for hepatic adenoma and focal nodular hyperplasia.

Benign liver tumors are relatively uncommon and, even when large enough to be symptomatic, they usually remain undiagnosed prior to exploratory laparotomy. Hemangiomas constitute the majority of benign hepatic neoplasms and are 9 times as frequent in females as in males. Most are asymptomatic but abdominal swelling, a mass, or symptoms due to compression of adjacent organs may occur and abdominal hemorrhage is reported in 4.5% of patients. Hepatic hemangioma may produce a large arteriovenous communication serious enough to cause heart failure. Recently an increased frequency of liver tumors, mostly adenomas, has been noted in women taking oral contraceptives (OCs); the cause has been attributed to estrogens. The exact incidence is unknown but believed to be low. It is most common in women in their late 20s who have been on OCs for 7 years or more. The tumor occasionally completely regresses on withdrawal of the OCs. The tumor may be discovered incidentally at laparotomy or may manifest inself by pain, a palpable mass, or catastrophic hemoperitoneum. Hepatic adenoma is usually a solitary lesion and infrequently degenerates into malignancy. Differential diagnosis includes chronic gall bladder disease and peptic ulcer. Focal nodular hyperplasia (FNH) is apparently much less frequently related to OC use and is less likely to bleed seriously than adenoma. Hepatic chemistry is usually normal in adenoma and FNH, but slight increases in serum bilirubin, serum alkaline phosphatase, and serum transaminase may occur. Primary liver cancer (hepatocellular carcinoma or hepatoma) is mostly a disease of males and in the US and Western Europe seldom develops before age 40. Fibrolamellar carcinoma, which characteristically develops in adolescents and young adults, occurs with equal sex incidence. Doubt has been expressed about its relationship to OCs. In the US about 75% of primary hepatocellular carcinomas are associated with cirrhosis, and about 5% of cirrhosis cases develop primary liver cancer. Clinical manifestations of hepatoma have been divided into 5 groups: frank cancer (62.7%), acute abdominal cancer (8%), febrile cancer (8%), occult cancer (16%), and metastatic cancer (5%). Detection of large amounts of alpha fetoprotein has proven useful in diagnosis of hepatocellular carcinoma, but values may be negative in OC users. It has been estimated that 1/3 to 1/2 of all malignant tumors eventually metastasize to the liver.

We present the case of a 25-year-old woman who developed a large central liver adenoma after 8 years of continuous oral contraceptive use. The first diagnosis was made by ultrasonography, after a rise in plasmatic gamma-glutamyl-transpeptidase and alkaline phosphatase levels was noted. Withdrawal of the oral contraceptive was followed by shrinkage of the adenoma, with complete disappearance 9 months after the diagnosis. Hepatic adenoma (HA) still presents problems in terms of differential diagnosis and clinical management. There are reports of complete or partial regression of an HA after discontinuation of oral contraceptives, but they are poorly documented. To our knowledge, a patient with such rapid disappearance of a large HA has never been reported.
