Scaly skin in girth area?

[little_critter]

My boy started off with a scabby area in one spot under his girth.
I thought it was a girth rub so changed girth, added a fluffy sleeve and kept a close eye on it.
The initial area mostly healed up, but remains scaly. This is despite him not wearing a girth at all for 2 weeks.
He now has other patches of scaly skin in the girth area, and some up in his armpits (where his girth doesn’t even touch)
So now I’m not so sure the original scab was girth related.
He’s in very light work and almost never works up a sweat, or even a damp patch so I’m not sure it’s sweat related.
Despite this I’m making sure i carefully wash off the area after riding.
Any thoughts what it could be? And what else I could do about it?
(the careful washing has only started in the last few days so I doubt I’m drying out the skin through over washing)

Potentially sarcoids. I know a horse that got them in that area. They can present as bald patches of skin too.

Hmmm, he’s due his jabs soon so might ask vet to take a peek.

My friends cob has this in his armpits, shes tried everything including the vet, its a form of dermatitis. But he is happy enough with sudocrem or summer fly cream. I use battles summer fly cream as its antiseptic and keeps the area fly free and supple

Until the vet takes a look, is it worth patch testing and then using an anti-chafe cream such as that used by runners/cyclists? I highly recommend Happy Bottom Bum Butter (yes, really) and you don't HAVE to use it on a bum...

I've seen flat sarcoids there a few times

Could it be ringworm?

Girth gall?
