[A Resected Case for Needle-Tract Implantation after Radiofrequency Ablation to the Hepatocellular Carcinoma].

A 82-year-old female had received radiofrequency ablation for hepatocellular carcinoma(HCC)in segment 2 30 months before surgery. One month before surgery, enhanced CT showed enhanced lesion about 20 mm in diameter in the abdominal wall along the needle-tract. There was no other recurrent lesion including liver. We diagnosed the lesion as needle-tract implantation and she underwent surgical resection of the abdominal rectus muscle and sheath including needle-tract. The pathological findings revealed well differentiated HCC. After the surgery, she underwent transcatheter arterial embolization for the recurrent HCC in segment 3 and segment 4. Twenty one months after the surgery, she has been alive without recurrence. Our case demonstrated that surgical resection of the needle-tract implantation of the HCC is one of the useful therapeutic options for the selected patients.
