Colorectal cancer metastases occur predominantly in the liver, with extrahepatic sites being far less common and equally distributed in the lung, brain, skin, and bone. We report two cases of unusual bony metastases of colorectal cancer. A 55-year-old man underwent an abdominoperineal resection for a Dukes B carcinoma of the rectum, followed 17 months later by a right hemihepatectomy for metachronous liver metastases. He subsequently presented 11 months later with a solitary metastatic deposit in the mandible. Seven months after resection and reconstruction, he remained well and disease-free. A 67-year-old man underwent a right hemicolectomy and right hemihepatectomy for carcinoma of the cecum and synchronous liver metastases. He presented 16 months later with a lesion suspicious of metastases in his clavicle. He subsequently died 18 months after his original operation. The prolongation of survival after hepatic metastasectomy results in the presentation of metastases at sites not commonly seen in colorectal malignancy. Postoperative surveillance after apparently curative hepatectomy should be directed to the evaluation of any unusual new symptoms.
