Rectal metastasis following radiofrequency ablation for hepatocellular carcinoma

Summary Radiofrequency ablation is a procedure used to treat hepatocelluar carcinoma. In this paper, we describe an unusual case of solitary rectal metastasis in a 71-year-old male patient one year after he had undergone radiofrequency ablation for hepatocelluar carcinoma. His presenting symptoms were tenesmus and the passage of small-caliber stools. The definitive diagnosis was determined after he underwent laparotomy. The liver and the abdominal cavity were free of the tumor, except for the rectal lesion.
