• Bile duct adenomas can be difficult to differentiate at laparotomy from small metastatic tumor nodules in the liver. This can present a problem to the pathologist and surgeon relative to the advisability of attempted curative vs palliative surgery. We report two such cases. Review of our autopsy materials shows the incidence of bile duct adenoma to be higher than usually reported. Even though they all present as grayish-white, firm nodules, usually frozen section will reveal the true nature of the lesion. Occasionally, however, the lesions with active bile duct proliferation can cause problems in diagnosis, even after such examination. Accurate diagnosis by recognition of the entity and its histological characteristics may be very important in the surgical treatment of patients.
