A Case of Needle Tract Seeding of Hepatocellular Carcinoma after Percutaneous Ethanol Injection Therapy; Needle Tract Seeding after Percutaneous Ethanol Injection Therapy / 대한간학회지

ABSTRACT

The tumor seeding after percutaneous ethanol injection (PEI) therapy has been considered to be a rare complication in hepatocellular carcinoma. We report a case of needle tract implantation of hepatocellular carcinoma following PEI manifested as subcutaneous nodule. A 57-years old male patient had been treated with PEI for hepatocellular carcinoma. Thirteen months after completion of the PEI session, a subcutaneous nodule was palpated at the site of the needle puncture. A CT scan showed that the subcutaneous nodule was 1.7 cm in size and enhanced in the early phase. The nodule was surgically removed. Microscopic examination showed hepatocellular carcinoma.
