수술 8년 후 간내 재발없이 골반골부위 전이로 발견된 간세포암종 1예

Abstract

In hepatocellular carcinoma distant metastasis after curative surgical resection without intrahepatic metastasis is very rare. A 55-year old man presented with a huge pelvic bone mass. Eight years ago he underwent posterior hepatic segmentectomy following diagnosis of hepatocelluar carcinoma. He has received regular check-ups with abdominal ultrasonography and serum alpha-fetoprotein. On admission an MRI on the pelvic area showed an 18×10 cm sized lobulated mass invading the pelvic bone and acetabulurn. Microscopic examination revealed that the tumor was a well differentiated hepatocellular carcinoma. There was no evidence of intrahepatic recurrence. He was treated with transarterial chemoembolization, extemal radiotherapy (total 3750 cGy), and systemic chemotherapy using 5-fluorouracil.
