Three cases of androgen related primary hepatic tumor in non-Fanconi patients are described in whom detailed information is available concerning histologic changes and clinical course over long periods. Two patients presented with hepatic rupture and hemoperitoneum requiring surgical intervention. In one case histologic assessment showed a hepatic adenoma which has almost completely regressed over four years since androgen withdrawal. In two patients there was a degree of nuclear pleomorphism not seen in 'spontaneous' adenomas and following androgen withdrawal there has been no evidence of progression or of metastases although the tumor has not regressed over a follow-up period of two years.
