Note regarding the removed tumor:

I am in possession of slides (tissue samples) of the removed tumor in the event interested pathologists may wish to look at them.

The slides are stained (HE) as well as unstained in case interested pathologists would wish to do other tests on it.

From the laboratory in Germany, I have been informed that pictures of the slides can be performed by pathologists either digitally (if they scan the slides) or with a conventional microscope camera.
