Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and is the leading cause of death among patients with cirrhosis in Europe and the USA. US-guided percutaneous ablation, with either percutaneous ethanol injection (PEI) or radiofrequency ablation (RFA), is currently regarded as the first-line approach in the treatment of early-stage HCC deemed unsuitable for surgery or liver transplantation. RFA of focal liver lesions is considered safe and effective and has a periprocedural mortality rate of 0.3 %. Major complications occur in 0.9 – 2.5 % of cases and the most common ones are peritoneal bleeding, neoplastic seeding along the needle track, liver abscess, intestinal perforation and bile duct injury (Livraghi T et al. Radiology 2003; 226: 441 – 451; Giorgio A et al. Am J Roentgenol 2005; 184: 207 – 211). Major complications include skin burn at the ground pad site. This complication has been reported to occur in about 0.2 % of cases, but the risk seems to increase with the use of a high-current RFA technique if the surface area of the ground pad is not increased (Rim H et al. Radiographics 2003; 23: 123 – 134). In contrast, the occurrence of skin burn at the point of needle entry into the abdominal wall is very rare. The following provides a report of a peculiar case of serious skin burn at the needle entry point requiring major therapeutic intervention.
