Liver resection for hepatic adenoma

Between 1970 and 1978, eight hepatic adenomas were resected. Four of the eight patients took oral contraceptive pills before the hepatic adenoma was identified; one patient was male. Four patients had evidence of bleeding at the time of presentation. The original histologic diagnosis in the first five patients was malignant hepatoma. There has been no known recurrence of tumor and all patients are well. The use of oral contraceptives in these patients has been prohibited. Formal anatomic resection is recommended for hepatic adenoma when this procedure can be done without mortality or serious morbidity; however, in the future, less drastic treatments, such as occlusion of the hepatic arterial circulation to the tumor or discontinuation of oral contraceptives, may prove as effective as tumor resection.
