Abdominal wall implantation of hepatocellular carcinoma

BACKGROUND: Percutaneous fine needle aspiration cytology (FNAC) became a popular method for diagnosis of hepatic masses. Abdominal wall implantation from FNAC is rare. CASE PRESENTATION: We report a female patient who presented with a right upper abdominal wall mass 3 years following a fine needle aspiration cytology (FNAC) and resection of a solitary hepatocellular carcinoma (HCC) from the liver. The mass proved to be a metastatic HCC; it was locally resected with safety margins. To date (20 months later) she remains well with no recurrence. CONCLUSION: Implantation of tumor cells after FNAC for HCC is rare, but can happen. The availability of dynamic imaging of the liver should reduce the need for this technique in the diagnostic workup of patients suspected of having HCC
