Focal nodular hyperplasia (FNH) of liver in children

Abstract

Introduction: Focal nodular hyperplasia (FNH) is one of the rare benign tumors of liver and second common benign tumour after the haemangioma in adult. It is mostly seen in young middle age women.The actiology of this tumour is unknown; however congenital vascular malformation or vascular injury to the hepatocytes has been suggested as the underlying mechanism for hepatocellular hyperplasia. Its relation with OCP is still controversial2. The tumor is asymptomatic most of the time and detected during routine physical examination or incidentally during radiological investigation. Large lesion presented with abdominal mass and abdominal pain due to pressure effects over surrounding tissue. Only Symptomatic lesion needs treatment. Bleeding and torsion can occur but malignant transformantion never occur in this disease. FNH is very rare in pediatric population Here we report two case of such rare case in pediatric population. Hepatic resection was undertaken in both patients with excellent outcome.
