Hi,

I have a 9 year old Thoroughbred mare who developed a hard lump situated on her head between her eyes, slightly to the right. This appeared 2 months ago and we assumed she had been kicked. We took her to a vet who didnt appear to know what it was. She had no temperature, no visible puncture wound and the lump appeared slightly tender to touch. The vet mentioned a condition where the bone became inflamed and prescribed bute. This has had no effect. I am worried that my 3 year old thoroughbred gelding has developed a much smaller lump in a similar area on his head. Please can you tell me what this may be?

Thanks
Sheryl

If the the lump on your horses head continues to grow take her back to your vet and have then recheck her. It could be several things, eg, normal growth, tumor (unlikely in a young horse), sinusitis, or a possible nutritional problem. You need to be more specific about where the 3 year old TB gelding is developing a lump. Young horses frequently develop lumps under their jaw which is nothing more than their teeth growing.
Thanks,
Dr. Lowder
