Introduction:
Extragonadal germ cell tumors occur much more commonly in males than in
females and are usually seen in young adults(1). These are aggressive
neoplasms and can arise virtually anywhere, but typically the site of
origin is in the midline (mediastinum, retroperitoneum, or pineal
gland). The diagnosis should be considered in any patient with a poorly
defined epithelial malignancy, particularly young individuals. They are
also associated with a high tumor burden on the diagnosis. (2,3) Yolk
sac tumors of the liver are extremely rare and may not be considered
until the biopsy is performed. In young patients with multiple liver
lesions, one of the differential diagnoses to consider is the yolk sac
tumor. We present one patient with multiple liver lesions which mimicked
multifocal liver lesions.
