Conclusion:
Yolk Sac tumors are rare germ cell tumors that are extragonadal and rarely present in the Liver. The yolk sac tumor of the liver can mimic other liver lesions such as hepatocellular carcinoma and metastatic lesions. Imaging and tumor markers are helpful but the ultimate diagnosis of yolk sac tumor is made by histology. Metastatic yolk sac tumor of the liver has a poor prognosis. Physicians evaluating multiple liver lesions with elevated AFP, especially in young adults should consider germ cell tumors such as yolk sac tumors as a differential diagnosis.
