[Subcutaneous seeding of hepatocellular carcinoma after fine-needle percutaneous biopsy].

Subcutaneous tumor seeding after fine-needle percutaneous biopsy for hepatocellular carcinoma is a rarely seen complication. The authors describe a case of subcutaneous neoplastic seeding in a 70-year-old woman with chronic hepatitis C virus complicated by hepatocellular carcinoma. Ultrasonically guided fine-needle aspiration biopsy was performed in segment II of the liver. The neoplastic seeding developed along the needle track used to carry out the fine-needle biopsy. The subcutaneous tumor was excised, and histological examination revealed a well-differentiated hepatocellular carcinoma.
