Come to booth 71 at #USCAP2026 to see our new Atlas of Non-Neoplastic Bone Marrow. It’s been an amazing teaching resource! #hemepath #flowedu

Wonderful resident here @BUMCpath suggested that these should be called Auer Needles instead of Auer Rods or Bodies.

Nice case of Acute Promyelocytic Leukemia.

Null status for which blood group causes stomatocytosis?

What could be cooler than to see your very own @UMichPath @umichmedicine #hematology lab crew using the new #Rodaks hematology text 🎉🎉🎉

[Brian Adkins @path_brian]

What are these? What do we know about the patient's spleen (or lack thereof!)?

[Mark Girton @mark_girton]

@path_brian Thanks for targeting this finding.

[Mark Girton @mark_girton]

@path_brian All schistocytes are special. That being said, I report if >1 per hpf (100x obj). However, I often reduce this threshold if I also see frequent fragments. Not sure if this is helpful, but it sure is descriptive.

Low levels of vitamins B12 and B9 are primary causes of megaloblastic anemia.

A few years ago, I got temporarily stumped by the morphology of these circulating leukocytes...

Any guesses what these cells are? What's the diagnosis? #hemepath #hematology @umichtpath #UMichPath

Here's an image from a patient with myelofibrosis. When you see tear drop cells, how do you know they're genuine and not an artefact? 🤔

Anyone want to guess what is happening with this blood? No it's not clotted 🩸🤔

@lilyfromtexas No worries. Working with a couple friends, I used to "borrow" shopping carts and drop them off on the front lawn of one of my high school teachers. Did we get stopped by the police once? Yes. Could we have gone to jail? Probably. We both did some stupid stuff.
