Translation - English-German - sacrococcygeal teratoma

The original English "sacrococcygeal teratoma" is translated by frajofu to the German "Das fetale Steißteratom", which has added meaning: "The fetal sacrococcygeal teratoma". And, for what it is worth, the German term "Steißbeinteratom" is a little more common than "Steißteratom" (ratio 3:2).

On the whole, I think this translation was too mechanical, and I would like to reject it.

Here is my translation:

Steißbeinteratom; Keimzelltumor präsakrale der Typ Nicht-Seminom

But I didn't it "mechanically" - I read a lot of textes about this, and found this therm. I'm not a medical!
=> Make a correcture, notify-me, but rejection for a translation, for what I'd took half an hour is unfair.

I did not reject this translation; I cannot reject it, nor correct it here, because it has already been accepted by a third person. I am not concerned with rejecting it, so much as I wish there were a mechanism to *retract* and accepted translation.

I've edited the translation.

frajoju told me that there is gramatical problems with this translation. frajoju, feel free to edit it again
I think that with your knowledge of german and the medical knowledge of Una we should manage to get a perfect translation here

Almost there. More elegant than my own translation. I can work with it.

But again, I must point out that an important element of a good translation is that it does not introduce information not in the original. The adjective "fetale" in the translation is a significant error.
