Submitted image shows good labelling of endothelium of larger blood vessels. Capillary positivity is not easy to see at this section thickness ( 5 microns) and with this brightfield method ( IF should give a far better contrast ratio). In the submitted image VWF is clearly seen in the High endothelial venules of the lymphoid nodule. I presume that the black pigment is inhaled carbon.
