Descriptor disgerminoma
Scope note: Neoplasia ovárica maligna, que se considera derivada de células germinales primordiales de la gónada embrionaria sexualmente indiferenciada. Se corresponde con el seminoma testicular clásico, siendo idéntico a este macroscópica e histológicamente. Los disgerminomas constituyen el 16 por ciento de todos los tumores de células germinales, pero son raros en niños menores de 10 años, aunque cerca del 50 por ciento ocurren en menores de 20 años. Generalmente se considera que tienen bajo grado de malignidad, pero el tumor puede diseminarse si traspasa su cápsula y afecta a los ganglios linfáticos o los vasos sanguíneos.

Scope note: 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.
