Here are pics of a hoof I trimmed today. Elderly pony, probably has Cushings (untreated). Odd growth inside the wall at the toe on his RH. I think it is a keratoma, but I've never seen pics and figured that people here have either seen one or know what one looks like.
I took a side view pre trim. The opposite hind had normal angles, even though he's overdue for a trim. The next shot is after cleaning with a hoof pic, and it shows a cylinder of tissue poking beyond the sole to the height of the wall. Third shot is after the first couple of nipper cuts to show the tumor/growth. The fourth is of the hoof, not quite finished, but at least more normal. The last shot is how it looked after I'd taken the hoof down more to give him a better angle. Sorry they aren't in better focus. I've got vertigo today and my hands were shaking. Ugh.
Please note that the trim shown isn't final. I got him close, then did the other feet and came back to finish after he'd had a chance to get used to it. He was standing more comfortably by the finish--he has a tendency to stand with that foot forward. This is the second time I've trimmed this pony, so I was prepared with my camera.

Reason: Subject/Verb agreement. Ugh!
Not experienced with this. I don't think a vet will be consulted. Pony is ancient and has bigger problems than this hoof. I'm sharing for my own edification and for others who may be interested in learning. I figure somebody here has seen one. Heck, there's probably nothing new on COTH. But it is new to me.
I didn't say how long overdue he was. It is partly my fault, since she called a couple of months ago. The message got lost. Unfortunately, people have to be persistent with me.
Interesting! One of mine has a keratoma, found by my farrier, confirmed by my vet school. Hers presents as a black ring in the sole - almost like a very regular blown abscess outlined in black.
Xrays showed a conelike keratinous structure up inside the hoof, but nothing visible to the eye. She is sound on it, vet school advised me that while they could remove it, it would take quite a while of keeping the feet completely clean while it grew out, so we are going with monitoring and benign neglect.
Hmm. Would keratomas be at all related to melanomas? Keratoma pony had a lovely half brother, also grey, who got malignant melanoma last year.
It looks typical of the hoofwall Keratomas I have seen in the past.
There is nothing that can be done for it by a farrier or trimmer.
If it gets large enough to impinge on inner structures and cause lameness , it must be surgically removed by a a vet. That usually involves resecting an area from coronary band to the ground.
