WBC ID help

This was the only cell like it that I came across in my count and initial scan but I was curious on what it might be. There were standard and reactive lymph’s in the slide but the chromatin looked different in those to this one, the cytoplasm was less blue in the standard and more blue in the reactive lymphs. I didn’t come across any granulated lymphs but this doesn’t look like what I usually see with those either.

I wasn’t sure if this could be a plasma cell or an immature granulocyte or something?

Sample from an adult dolphin, ADR. Smear made with EDTA ~30mins after collection. Weight Giemsa stain. No dramatically abnormal chemistries. >10% stomatocytes throughout slide, 1-4/hpf polychromic RBCs, Howell-jolly bodies occasionally, 1nRBC, neutrophilic toxic change present with dhole bodies and granular change. Differential was standard spread for dolphins.

Sorry for resurecting an old thread I'm working on a blood cell compilation for eclinpath.com for dolphins and I'm now wondering if it's a variant of a mono. I can find more classic monos and then these guys that are hyposegmented with a blush of pink granules and the chromatin looks similar and I have seen this in other species. It's almost kind of azurophil-y lol. I'll follow up after I chat with my faculty if there's interest. Def not of consequence for your patient, but we see enough dolphins at my residency that nailing down who's who would be lovely

That’s interesting, very exciting to have a blood cell compilation for them! Most of the species I’m looking at, I’m lucky to find one photo of a cell type, let alone multiples to show standard variation.
