CONTRACEPTIVE-ASSOCIATED HEPATIC TUMOR

Many reports have associated oral contraceptive use and increased incidence of benign hepatic tumors in young women. These tumors can usually be classified as either benign hepatic cell adenoma (liver cell adenoma, hepatic adenoma) or focal nodular hyperplasia (hamartoma). Most lesions have been totally resected. Occasionally a lesion has only been biopsied, which allows its natural history to be observed. Spontaneous regression after withdrawal of oral contraceptives has occurred and has been documented by followup clinical examination and/or isotopic liver scanning. A patient in whom regression of a benign hepatic tumor is documented by angiographic as well as isotopic follow-up is reported here.
