Post liver transplant presentation of needle-track metastasis of hepatocellular carcinoma following percutaneous liver biopsy.

Hepatocellular carcinoma (HCC) is one of the few malignant tumours often treated without prior histological confirmation (in the patient with cirrhosis). Contrast-enhanced cross-sectional imaging is frequently diagnostic of HCC with a high degree of accuracy. However, on occasion, a liver biopsy is required, a complication of which can be needle-track metastasis. We present the case of a 57-year-old man who had previously undergone a liver transplant; he was found to have abdominal wall metastasis at the site of a prior percutaneous biopsy. This is the second case until now date of needle-track metastasis that presented following liver transplantation.
