Localized congenital hepatic fibrosis presenting as an abdominal mass

A six month old male with a liver mass localized to the right lobe that had the histological features of congenital hepatic fibrosis is presented. The mass was resected and the patient was asymptomatic 10 months after surgery. This case serves to further broaden the range of lesions with the histological features of congenital hepatic fibrosis; only one other example of localized congenital hepatic fibrosis has been previously reported.
