I've noticed this year on the 3 deer that I've cut up that they have a grey mass in thier fat that sort of looks like a oyster (for lack of a better description). Can anybody tell me what this is?

Could be an old injury...do you have any pics???

I think i know what your talking about, i've found it on several deer that i've shot, i'm not sure what it really is, if its abnormal growth or a tumor or what, it doesn't seem to affect the quality of the meet though

I have seen that stuff. My grampa always called it a fluke. I don't know if that is the scientific term or not. I have also seen it in the liver, but only a couple of times.

A guy I know called them a syst, but I find them in almost every deer, so I think it is a gland of some kind.

They won't hurt you or I would have been dead a long time ago.

Don't know what it is but I've found it in every deer I've cut up that I paid attention to. Especially in that big chunk of fat right in front of thier hind leg, and I think also in the chunk of fat up around thier neck/shoulder area.

Ive seen them too, and I think they are in all deer, or at least about every one Ive cleaned. I always find one in the fat right in front of each hind quarter, and also in fat between the shoulder and rib cage, Im not sure what they are, but they are in all the deer I cut up, do deer have lymph nodes?? I dont know, but theres nothing wrong with your deer.

wow rybo,,, we posted at the same time, I could have just waited, and said "ditto" lol

I bet it is a lymph node, I never thought of that.

I agree they are lymp nodes or glands. All deer have them.
