    Has anyone had a bone biopsy done?

    I have a horse with the strangest bone "ball" on his Right hind cannon bone. Vet xrayed and its just a mass.

    Over the last month it has doubled in size.

    Horse is not off, but he is a bit sensitive to palpation. It is warm to the touch. I have been icing and wraping daily and it is still growing.

    This is the strangest thing I have seen. I was thinking of taking him to San Luis Rey but worry about EHV... since here in our area is going around.

    My horse has a huge bump on his cannon bone, radiographed etc. Vet wasn't alarmed, said he probably got it from kicking the stall door. Surpassed, poulticed, banamine, and wrapped. It took several months till it stopped growing and the heat was completely gone. Most likely it's nothing

    This is just what my vet said over a month ago... but since it has grown so large we are concerned.

    How large was your horses lump?

    We originally thought it was from kicking his stall too but the growing deal is really puzzling.

    thanks for sharing your experience it sounds a lot like what I am dealing with and Im trying not to panic....

    I guess this means you're sure it's not a splint. Do you have new pictures?

    No, haven't experienced that. At least not yet. But as sure as I say that, Star will figure out how to get one. Sure hope you can figure out what it is and how to treat it.

    Vet xrayed said it was bone not a splint. No fracture either.

    I do have new pix

    My horse's is the size of a golfball. It started out small (hardly felt it) and had a rough texture, the bone then remodeled, growing in the process until it smoothed out. It took months for entire process. If your horse is not lame I would not biopsy it, you will only cause more new bone formation.

    Has your vet recommended shock-waving it or freeze firing it. Both of those will make it stop growing.

    My horse lives in wraps to protect his legs.

    Thank you sooo much for posting here. This is a strange issue that google doesn't bring up anything..

    The vet thought we should re xray and possibly inject with a corticosteroids.

    I will ask her about shock wave or freeze firing...

    As far as living in wraps... My hubby got a bunch of large 4 x 4 ft 4 inch thick solid rubber mats from a job. We demoed 10 Burger King play lands and these are the pads the kids climb up the slides. I thought about putting those on the corral walls so if he kicks it will be padded..

    I already wrap the fronts every night with bed boots because he rubs sore on his pastern joints if I dont.


    THANKS for your help!!!

    Usually "cancer" will show up as a lytic lesion in the bone. What do the radiographs look like?

    A good friends horse had an osteosarcoma (cancer) in the distal radius/ulna region. They neverknew it,horse never took a lame step until he laned off a small jump and his leg broke. During radiographs they noticed that it was a fracture at a lytic site. The bone (on necropsy) was biopsied and it was an osteosarcoma, a rare but aggressive bone cancer. No visual lumps on the horse, but the radiographs revealed a lumpy lytic area.

    Might be worth getting rads onyour guy to a radiologist for review - if its "solid" bone I would be much less concerned...but a radiologist may be able to give you a better diagnosis before a biopsy is done

    I had xray done about a month ago and am having a second series done tomorrow.

    The original xrays showed a mass of bone on the cannon bone. At this time I didn't notice any thing that appeared to look like a lytic lesion (understand that looks like the actual bone has been eaten away?)

    We are going to send the xrays to a specialist and go from there.

    Thank you so much for your help and agree before a biopsy is done because it seems like that would be very agressive if it's not necessary.

    I second this.

    Osteosarcoma is ridiculously rare in horses, and usually found in the axial skeleton (head/spine; almost exclusively the head), not the appendicular skeleton. If it turned out to be osteosarc, your horse would definitely make it into a research journal as a case study for sure.

    I would assume the lesion is some sort of periosteal reaction secondary to an injury.

    We had a large TB at our barn that started growing what we thought was a splint, but it just kept growing. It was technically never diagnosed as anything other than a splint, but since it wouldn't stop growing and was on the inside of the leg where it would interfere with the other leg, our vet did surgery to remove the bump. After surgery we had to spray a steroid/dmso compound in the area where the bump was removed to inhibit it from starting to grow again. That seemed to work and the horse was fine after his rehab from surgery.

    The rapid bone growth is what was so worry-some.

    But todays xrays showed the bone was about the same size and the growth was tissue. It is inflamed possibly because the bone growth is between the cannon bone and splint bone.

    We injected it with corticosteroids and will monitor it over the next few weeks and do xrays as we go to keep an eye on this.

    Yeah, I read bone cancer is really rare in the leg - but losing two other animals to some weird cancer issues you just never really know.

    I had a horse that was a wobbler and I had the bagby basket surgery perfomed and two years later horse had his brain stem punctured by a vet proceedure via necropsy. The Dr asked me if they could keep his neck where the Fusion surgery was performed for study because she said it was such a nice one and they didn't have any of those...... Ahhh OKay... I didn't want it for anything anyway......

    I have had some strange stuff happen to my horses.

    One of my old horses got a hole in his skull (a deterioration) and it was something these vets never had seen before.. Also another one of my horses was diagnosed with EPM via pressure point later verified by vets with a spinal tap.. many vets were surprised a pressure point could indicate EPM... my EPM horse is alive and well thanks to the vet/chiro that was able to act quickly with a starting diagnosis via a pressure point.....

    Thank you all for your posts, it has really helped me through this......

    Well that sounds like decent news. Hope that it doesn't grow more or do something else odd.
