NODULAR REGENERATIVE HYPERPLASIA AND FOCAL NODULAR HYPERPLASIA OF THE LIVER MIMICKING HEPATIC METASTASIS IN CHILDREN WITH SOLID TUMORS AND A REVIEW OF LITERATURE

Abstract

Nodular regenerative hyperplasia (NRH) and focal nodular hyperplasia (FNH) of the liver rarely occur in children after completion of tumor therapy. These lesions mimic hepatic metastasis and they must be distinguished from metastatic lesions. The authors present 2 children, one with NRH and one with FNH, after undergoing antineoplastic therapy for non-hepatic childhood solid tumors and discuss their patients in the context of the literature.
