Core Tip
Core Tip: Hepatocellular carcinoma (HCC) metastases are typically associated with increased tumor diameter, multifocality, and vascular invasion. We report a rare case of HCC metastasis to a portocaval lymph node with initially occult hepatic primary. Our case illustrates that multimodal evaluation including alpha fetoprotein and contrast-enhanced magnetic resonance imaging may improve the sensitivity of identification of primary HCC lesions. We also reviewed the literature for HCC presenting as extrahepatic masses (18 cases: Metastatic lesions; 30 cases: Primary ectopic HCC), and discuss that, in patients with extrahepatic sites of HCC, thorough assessment for intrahepatic lesions is critical to classifying disease as metastatic HCC or ectopic HCC.
