Management and surgical treatment for focal nodular hyperplasia in children.

Focal nodular hyperplasia (FNH) is rare in pediatric liver tumor. To investigate the experience in the appropriate management of pediatric FNH, the records of consecutive children who were managed at our institute from 2000 to 2007were reviewed for FNH. There were four males and nine females whose ages ranged from 26 months to 18 years with a mean of 11.7 years. FNH in most children was detected by medical examination for abdominal pain (61.5%) or other symptoms. All the 13 pediatric patients underwent liver resection. There was no operative death or postoperative complications. The children were regularly followed up ranging from 2 to 85 months and they were healthy without recurrence. For pediatric FNH patients with clinical symptoms or indefinite diagnosis, it is suggested that active surgical treatment by hepatectomy should be performed.
