[Histonet] false positive CD31?

[Gudrun Lang]

Dear histonet!

 

Has anyone seen granular, fine dot-like, cytoplasmic CD-31 staining in
tumorcells, that was thought to be false positive?

It looks like really specific staining, but my pathologist sent this case to
an expert, who couldn't reproduce this staining.

The expert is really an expert and his diagnosis is not to be bothered.

 

We stain with dako-ab on benchmark Ultra (CC1 mild, 32min plus amplifier,
1:50).

 

thank you
