Solitary Paraaortic Lymph Node Metastasis of Primary Hepatocellular Carcinoma which was Misdiagnosed as Primary Retroperitoneal Tumor

ABSTRACT

The prognosis of primary hepatocellular carcinoma is very poor, and a curative resection is capable only in few selected patients. Most patients die from tumor recurrence. The rate of intrahepatic recurrence of hepatocellular carcinoma is much higher than extrahepatic recurrence or metastasis. The most common site of extrahepatic metastasis is lung, and followed by lymph nodes, bone and adrenal gland. Common sites of node metastasis are celiac lymph nodes and hepatoduodenal lymph nodes, however paraaortic lymph node metastasis is very rare. Here, we report an experience of solitary paraaortic lymph node metastasis from hepatocellular carcinoma which was misdiagnosed as primary retroperitoneal tumor by preoperative imaging studies.
