Young roe
- Thread starter Dorset Deer
- Start date
I'd initially (first glance) have jumped to something like that but would expect those to usually be fluid filled. Depending on the age of the roe I wonder if they're normal developing immune tissue/nodes or potentially reacting to something, and could be fatty tissue there also. Some of the haemal nodes appear to have it too. Not something I've seen before but reminds me of the appearance of Peyer's patches I've seen in young lambs I've PMed which makes me think maybe it's normal developing tissue, or reacting to something.
@Dorset Deer if you can get the person who sent that to you to put one in alcohol (isopropyl or ethanol best but vodka will do in a pinch (I'm assuming you don't have access to formalin)), and send it to me I can get it confirmed with histology. It'll only cost them the postage.
It's worth noting that the normal structure of lymph nodes is lobular and the image looks like that's what we're seeing, although usually you'd not see the structure so clearly, especially grossly. Oversimplified diagram below (suspect human).

Looking again closely, they appear to be solely in the fat - I'm very much back thinking parasites. Detailed examination as you have proposed is obviously the best way to be sure if @Dorset Deer can arrange it. Thanks
I messaged a friend who is very keen on pathology. Would still love a sample if possible to confirm (plus we're both weird and have our own libraries of histo slides) but he said he found this image on a butchery Q+A page where it was described as normal haemal nodes.
EDIT: I still wonder whether it's reactive and the appearance is due to proliferation of immune cells in their lobules, hence the paler patches.

that was my initial thought too.
Yes. Does seem odd doesn't it. Hopefully we can get a sample.@WW. Surprised there no more regular sightings of these then - first I've ever seen in hundreds of animals across all 6 species
Pretty sure these are lymph nodes “within normal limits” probably just reacting to normal challenges. As WW says, histology would be most excellent. It would be good to get some funding to do some histo on the samples you folk find
Bits as requested have been sent off.
Looking forward to the findings.
I followed this up with a Senior Lecturer in Veterinary Public Health I'm acquainted with.
His response:
The pictures do look like haemolymph nodes. The research suggests that they have a similar action to the spleen and can be sporadic but mostly associated with the kidney fat up to the pelvis. Not an issue as far as I am aware.
