Focal nodular hyperplasia (FNH) is a benign lesion of the liver characterized by focal hyperplasia of hepatic parenchyma with a central scar of fibrosis around an abnormal artery. FNH is an asymptomatic mass that is often detected, that should be differentiated from hepatic adenoma and hepatocellular carcinoma. The clinico-pathological features of 24 patients with symptomless FNH incidentally detected by abdominal ultrasound (US) is described. FNH nodes are usually discovered incidentally during US examination performed in patients complaining a specific gastrointestinal symptoms. A 10-yr follow-up showed that the disease is not progressive and that surgical therapy is usually not necessary.
