During a routine preventive examination, a

65-year-old patient is found to have an asymmetrically enlarged liver. The

patient himself admits that he drinks alcohol regularly and is therefore

referred for an ultrasound examination of the liver. The examination reveals a

prominent mass in the right lobe of the liver and a biopsy shows hepatocellular

carcinoma. After further investigations, the patient undergoes surgery during

which the tumour is removed. To confirm that the entire tumour has been

removed, including a sufficient margin of surrounding healthy liver tissue, the

resection is sent to pathology. What epithelium makes up the rim of healthy

liver tissue?
