Core Tip

Core Tip: Undifferentiated embryonal sarcoma of the liver is rarely seen in clinical practice; it is difficult to diagnose and easily misdiagnosed before surgery. Comprehensive treatment based on complete surgical resection is the key for long-term survival. The methods for diagnosis, treatment, and prognosis evaluation of the disease should be further investigated.
