Needle tract implantation of hepatocellular carcinoma after percutaneous liver biopsy

Abstract

The authors report a case of needle tract implantation of hepatocellular carcinoma following percutaneous biopsy of the liver. The patient, a 62-year-old Japanese male, was found to have a small hepatocellular carcinoma diagnosed by needle biopsy; this was followed by transcatheter chemoembolization, a combination of transcatheter arterial infusion of adriamycin and transcatheter arterial embolization of Gelfoam, and right lobectomy. Eight months after the biopsy and the lobectomy, a nodule of hepatocellular carcinoma, measuring 3.5 cm in diameter, was found at the site of the previous biopsy and excised. The patient is doing well without further recurrence of tumor 23 months after the lobectomy and 15 months after the excision of the implanted tumor in the subcutis.
