DEF

Tumeur germinale maligne du testicule ou de l'ovaire.

CONT

La tumeur vitelline du testicule est encore appelée tumeur du sinus endodermique ou carcinome embryonnaire de type infantile, ou orchioblastome, ou adénocarcinome embryonnaire alors que la tumeur vitelline de l'ovaire ou tumeur du sinus endodermique, a été longtemps désignée sous le terme de mésonéphrome de Schiller ou de papillo-endothéliome ou de mésoblastome, en raison des ressemblances qu'on avait cru relever entre ses aspects histologiques et les glomérules du mésonéphrome, les proliférations endothéliales ou les mésoblastes de l'embryon.

OBS

La tumeur vitelline se développe plus souvent à l'état pur dans l'ovaire que dans le testicule.
