Intraoperative Evaluation for Extracolonic Disease in Colon Cancer Patients

Part of the Frozen Section Library book series (FROZEN, volume 4)


Although radiographic studies usually provide accurate preoperative staging information in colorectal cancer patients, intraoperative frozen section evaluation of extracolonic tissues may be requested in order to confirm the diagnosis of a metastasis or ensure its complete resection. The liver represents the most common site of distant organ metastases from colorectal cancer. Several benign lesions may simulate liver metastases, most notably von Meyenberg complexes and bile duct hamartomas. Peritoneal carcinomatosis is also an important intraoperative finding that may alter the surgical management of colon cancer patients. A number of mimics of peritoneal carcinomatosis are encountered in the frozen section laboratory.
