Willy had a wart-like growth on his side that showed up fairly quickly a couple months ago and then fell off on it's own. Well, it regrew, so I showed it to his owner (the Barn Owner) to get her advice. She gave me some sarcoid cream (xxtera) to apply. The directions were once a day for 4 days and then once a week or so.
I ended up doing two consecutive days of treatment, one day without, followed by one day with. On the fifth day, which would have been the fourth application, I noticed the fur around the warty area was a bit crusty. I figured the cream had spread out some as I had been careful to apply it only to the wart itself.
I thought it best to clean the excess from the surrounding fur before giving the next treatment. So, I applied a warmwater facecloth to the area and began gently cleaning the fur. I alternated holding the cloth against him to soften and dabbing at the area. After 2 or 3 times, most of the fur was clean but for one small section.
I held the cloth against my horse one more time, rubbing his neck and admiring his shiny coat while I did so. When I removed the cloth, I noticed a small area of rawness opened up that hadn't been there before. I ever so gently dabbed just below it and was horrified that the top layer of skin seemed to be peeling off him.
It was as if it just melted right off. I was horrified at what I was seeing (and probably feeling more drama than I needed, but I was alone so no one else had to deal with it!).
I ended up with about 1.5-2cmx1cm half-moon area that was raw and slightly pussy under the wart. I cleaned this up and applied some Hibitane to the wound.
I drove home with a heavy heart and had nightmares all night. Can you say first time horse mom? I know I'm not really, but even his owners consider him my horse at this point. I spent a bit of time in the moring doing research on sarcoids and treatments and feel marginally better but I am also armed with other, less horrid, ideas.
This afternoon I went out to check on him.
This is what it looked like.
The sarcoid is the black circular area inside the raw area.
I saw the BO and told her about how I was devastated that I was melting the flesh off her horse. She said, "you mean your horse?", and then..."It's ok, that can happen with this stuff, relax, he'll he fine. I will come see him after I check on my spagetti sauce.". I was lunging him in the arena by the time she came out. We admired his back muscles working and then took a look at the area in question. She assured me that he wasn't about to lose a limb but to wait a bit before treating again.
In her opinion, nothing should be applied to the raw area because you want it to dry out. Personally, I'm quite sure recent research has shown that a petroleum-based antiseptic cream heals faster as it prevents cracking in the healing tissue. Opinions on this?
I cleaned the area of the dried pussy bits and applied a thin layer of petroleum based antibiotic cream on the raw area only. I need to do what I think is best and they have told me to do so whenever I see fit, since they know I don't make rash decisions. Still, I don't have a lot of experience of this level of care with a horse because I always had to follow other peoples orders, whether I agreed or not. Regardless, going forward I think I will apply some bag balm or something around the wart before applying the sarcoid cream, if I do have to treat again. Hopefully that will protect the surrounding tissue more.
