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.
