Hepatic focal nodular hyperplasia after liver transplantation: case report and review of literature.

Patients with decompensated cirrhosis complicated by hepatocellular carcinoma (HCC) or those who have undergone liver transplantation following liver failure after HCC treatment should continue to receive post-transplant surveillance. Any new liver tumor must be carefully evaluated to determine whether it is a recurrence of HCC. Focal nodular hyperplasia (FNH), the second most common benign hepatic tumor, is believed to result from the hyperplastic response of hepatocytes to pre-existing vascular malformation. Here, we report a case of hepatic FNH two years after living-donor liver transplantation in a patient who experienced liver failure following treatment for HCC. Given the rarity of hepatic FNH after liver transplantation, we present this case along with a review of the literature.
