Definition / general
- Mixed germ cell tumor with multiple embryoid bodies (central core of embryonal carcinoma cells, amnion-like cavity and yolk sac tumor component)
- Elements other than the embryoid bodies, however, should constitute less than 10% of the tumor for the 'polyembryoma' designation to be used (Mod Pathol 2005;18:S61)
- Resembles embryonic yolk sac
- Behaves like other mixed germ cell tumors
