First described by Dr. Anna-Luise Katzenstein

Mid-40’s male w/nasal obstruction

Dx: allergic fungal sinusitis (polyps not shown)

📸 layering of mucin, cellular debris, degranulated eosinophils & inflammatory cells
📸 Charcot-Leyden crystals (arrows)
📸 occasionally fungal forms visible on H&E (arrow)
📸 fungus readily highlights w/GMS

So many eosinophils in this case of tubulointerstitial nephritis secondary to recent antibiotic administration. Few tiny granulomas as well. Eos seen in EM as well. #renalpath #pathsky #nephsky

Yes! The Davis/Thompson Foundation provides the infrastructure and storage for several veterinary Pathology groups; in return, they make their slides available at no charge.

We also have one of the largest repositories of veterinary gross pathology images freely available as well:

Thank you! 🙏🏾

Such a nice case! Thank you for sharing your expertise!

Wow the WSI is spectacular! Open access?

We see those!

Mucicarmine highlights these beautifully.
