Hepatocellular carcinoma is one of the most common causes of cancerrelated death worldwide. In cases of liver resection for hepatocellular carcinoma, the dissector, whether a pathologist' s assistant, physician, or resident, must have a clear understanding of both the terminology of liver anatomy and the requirements of the corresponding College of American Pathologists Cancer Protocol to properly orient, describe, dissect, and sample the specimen. This chapter provides guidance for the gross dissection procedure for the production of a valuable pathology report, which is of key importance for a patients' ongoing care.
