6/n so, we applied the PB stain and this is what we found: clear evidence of WBC casts, mixed with some granular, and other RTEC casts too. Were they missed earlier? Hard to say, but they were visible on this day. Steroids were started.

5/n so we pull the Prescott-Brodie stain out of the shelf. Stain revived by Ralph Mohty @rmohty.bsky.social Only WBCs are expected to stain blue, like in the images below. See this technical paper watermark.silverchair.com/gfae122.pdf?...

4/n unstained #UrinarySediment didn’t reveal much. Using Sternheimer-Malbin stain, we caught some cellular casts. Hard to be certain but they looked like renal tubular epithelial cells for the most part. Which would favor ATN as the primary culprit. But, we wanted more certainty…

Here is a bipartisan #pathology case. It's relevent to DVMs and MDs. Lots of red (at least pink) and blue, too.
Rhinoscopy and nasal biopsy from a dog. What’s your diagnosis? It's a classic.

Ooh, found a nice one to share from the ol' PathTwitter account. The buzzword for this diagnosis is a "jigsaw" pattern of nested cells. Thoughts?

The peripheral smear can give a preview of what you'll find in the marrow. Here we see a circulating blast, a nucleated erythrocyte, and anisopoikilocytosis with frequent teardrop cells. What do you think the marrow might look like? 🤔
