Hepatic adenoma. Observations after estrogen withdrawal.

A case of ruptured, benign hepatic adenoma occurred in a young woman taking oral contraceptives. Our observation of this patient after biopsy and control of hemorrhage is the subject of this report. We support the concept that these tumors may regress or remain dormant after estrogen withdrawal, and question the need for routine resection of benign hepatic adenomas. Further observations of growth patterns after estrogen withdrawal are needed.
