Abstract
Most benign biliary lesions are too small to be detected by imaging techniques, so their presence is not usually suspected prior to abdominal surgery. Unfortunately, their features can closely simulate the gross appearance of metastatic adenocarcinoma and, thus, they are often submitted for frozen section analysis during procedures to remove extrahepatic malignancies. Intrahepatic adenocarcinoma is a diagnosis that is either confirmed or suspected at the time of surgery in most cases, so intraoperative pathologic assessment of these tumors is limited to evaluation of surgical margins. The purpose of this chapter is to (1) describe the gross and histologic features that facilitate distinction between benign and malignant ductal proliferations in the liver and (2) discuss issues related to evaluation of hepatic resection specimens that contain cholangiocarcinoma.
