My friends horse has a white scabby skin in one ear - which someone on the yard has said looks like canker and suggested treating it with the same stuff you treat canker in dogs. I can't find anything in my vet book about canker so thought I'd approach the experts on the DG....
What do you think?

 They are called "plaques " and will go away with time. They are not a problem, and can be left alone.

Probably aural plaques. Our vets horse has them and he says there is no treatment, and I guess he'd treat them if he could as he doesn't need to bill himself! He says they are probably a combination of a skin tumour and in some cases, a fungal infection, but no one really knows for sure what causes them. There may be a viral component. They don't seem to bother the horse, they just look a bit unsightly.

They have been linked to developing sarcoids and I do know of an Appaloosa that had them and went on to get multiple sarcoids.
I thought the condition known as canker was caused by ear mites and as horses are routinely treated with ivermection, shouldnt think ear mites are a problem in horses?
Anyone?

Sarcoids have been loosely linked to cattle. Never heard of them being linked to aural plaques before. We've had two horses with sarcoids. Both developed them having been turned out in fields that had previously been used for cattle. We've got 3 horses here with aural plaques. One is much more severe than the others. None of them has sarcoids and they've had the aural plaques for some years now.
There is believed to be a viral component to both sarcoids and aural plaques but not the same viral component.

Yes very good photo
My TB/ID has these.
We do have black flies near the river--when they are bad horses are stabled
Sometimes he really enjoys his ears being rubbed inside and I do manage to get some cream on to soften the scabs but often he wont let me touch them
He has had the plaques for many years they have neither worsened or improved
The Connemara also gets black flies in his ears but his have never scabbed

someone at her new yard said they were plaques - so as usual, the IHDG experts are on the ball!
What sort of cream is good to soften the scabs? And is there anything that should be avoided - my horse has sarcoids and I know that Ti-tree should be avoided because it encourages cell growth and the last thing you want to encourage is the growth of sarcoid cells!

They aren't really scabs, although some of the flaky stuff will come off with a finger nail. There isn't really anything you can put on them. If you do try things, you'd obviously need to avoid anything that can fall into the ear canal. These plaques don't go away in my experience. You just stop noticing them after a while!

There's a very famous horse who has an ear full of ear plaques - I think it's Headley Britannia. They don't bother her, except that they have to be careful when bridling her, as she hates her ears being touched, apparently.
