Liver transplant for relapsed undifferentiated embryonal sarcoma in a young child

Abstract

Undifferentiated embryonal sarcoma of the liver is a rare hepatic malignancy of childhood with a historically poor prognosis. Recent improvements in outcomes have been reported in small numbers of cases with the use of combination therapy involving aggressive surgical resection and chemotherapy. Complete surgical resection is frequently difficult to achieve when the location of the tumor is along the margins of the major hepatic vessels (portal vein, hepatic vein, and hepatic artery). Here we report a case of undifferentiated embryonal sarcoma of the liver that recurred along surgical hepatic vein margins in a 9-year-old boy who subsequently underwent orthotopic liver transplantation from a cadaveric donor. The patient has been in continuous clinical remission for the last 5 years.
