Isolated positive cells mostly in capillaries and the mucosa

SImple squamous cells of  visceral peritoneum is positive. ? Specific?

I am not familiar with this protein but the positivity in this image is similar to that seen in HPA liver images ( albeit human)

I do not know if this specific: positivity in ? follicular dendritic cells?

Compare with anti MASH result.

Seems like there is division in migrating progenitor interneurone cells?

Positivity in nuclei of enteric plexuses

Should be further diluted.
