Undifferentiated embryonal sarcoma of the liver is a malignant mesenchymal tumor of the liver that predominantly affects children, with exceedingly rare occurrence in adults, and is associated with a poor prognosis. We present a case of Undifferentiated embryonal sarcoma of the liver in a previously healthy 45-year-old male, admitted to our hospital due to fever.Magnetic resonance imaging revealed a cystic-solid mass in the right lobe of the liver, measuring approximately 15*13*13cm in size. Imaging diagnosis raised suspicion of biliary cystadenocarcinoma with hemorrhage. A hepatic resection was successfully performed for the patient, and the histologic diagnosis was Undifferentiated embryonal sarcoma of the liver. The patient received a chemotherapy regimen of ifosfamide combined with epirubicin after surgery, and no recurrence was observed after 6 months of follow-up. We herein review the clinical, radiologic and pathologic features of this rare tumor.
