Signs and symptoms include abdominal pain and a large abdominal or pelvic mass. The serum alpha-fetoprotein is almost always elevated preoperatively. Morphologically, there is marked heterogeneity due to numerous patterns of differentiation coexisting in the same tumor. The most common pattern is reticular."
