Undifferentiated embryonal sarcoma (UES) is a rare and highly malignant hepatic neoplasm, affecting almost exclusively the pediatric population. A total of 63% of patients are between 6-10 years of age, and it commonly occurs in the first two decades of life. It has a survival rate of 40% at 3 years (O Sullivan et al. 2001 Lack et al. 1991).
