Hard lump on jaw bone

[Nightlife]

Last month my 21 yr old Thoroughbred came in from the field with 2 hard boney type lumps on either side on his jaw line... Had vet out who has x rayed it but they cannot find anything wrong but it is still there.... He has had his teeth checked and there are no problems. Has anyone got any ideas or had this before ????

Many thanks in advance

I don't know what that it but my horse had a hard lump on his nose the size of a pea. My vet said it was his brain Just diappeared a few months later.

The exmoor I loaned had a lump on his bottom jaw that had been there as long as his owner knew. Vets had no idea, it was definately bone, never caused a problem.
