Preferred Label : dysgerminoma;
Definition : A malignant ovarian neoplasm, thought to be derived from primordial germ cells of
the sexually undifferentiated embryonic gonad. It is the counterpart of the classical
seminoma of the testis, to which it is both grossly and histologically identical.
Dysgerminomas comprise 16% of all germ cell tumors but are rare before the age of
10, although nearly 50% occur before the age of 20. They are generally considered
of low-grade malignancy but may spread if the tumor extends through its capsule and
involves lymph nodes or blood vessels. (Dorland, 27th ed; DeVita Jr et al., Cancer:
