"I guess that a Gold Spot on a cremello could be mistaken for a Bend Or spot though "

Lol yea, didnt think that, any white/grey horses with gold spots?
So this is just a section of Diluted Pigment?

Some interesting ideas in there. As you can see from the pics in the first one, Gold Spots can look very different.

As far as his genetics causing it - it would be chimerism in that case, and would have been there at birth.
Oh wow, those links are interesting! The one spot on the bay (2nd picture in 5th post) looks very similar, though much larger, but it's got the same wibbly edges to the area. Fascinating stuff! Pretty sure there is no chimerism going on, I just can't fathom why it showed up now. Wanted to make sure I didn't need to worry my friend about cancer or something awful. Lol

Thyme, yup, like I said Lola has one on her side, it's perfect oval, and dark brown/blackish.

Is there any chance something bleached that spot?

I vote he was playing in the laundry room and he accidentally spilled bleach on his shoulder and did not rinse it out quick enough.

I have done that to some pants.


OK, I admit it, just subscribing to the thread because I am interested in the answer.

Could it possibly be a form of depigmentation in this case? I haven't studied the mechanism to see if that would even be possible. My father-in-law has depigmentation in his skin that appeared later in life.

From wikipedia
Quote:
Depigmentation is the lightening of the skin, or loss of pigment. Depigmentation of the skin can be caused by a number of local and systemic conditions. The pigment loss can be partial (injury to the skin) or complete (caused by vitiligo). It can be temporary (from tinea versicolor) or permanent (from albinism).

Yup, That's him, AGD Skips My Dad. From pictures I am guessing he is actually a sooty pali, which is kind of what I was wondering might be playing up here.

AB lol I told Tracie last night that Stiffler heard her, she always says that he is a "boring" color, so he grew something flashy to impress her.

Alforddm, Normally I would suspect that to be the case. But in the time we have had this horse here, there have been no injuries or trauma to that area. He has gotten plenty of bite marks on his back and hind quarters, (he's low on the totem pole). But so far they have tended to grow in dark and then sunbleach and match right back in. I know he hasn't had any injuries to that shoulder, so I don't think depigmentation is the case here.

Well depigmentation can be caused by other things besides trauma so that doesn't entirely rule it out. Given that his sire is a pally I wonder if he might be a "brownskin" (brown based buckskin) and for some reason the "brown" is getting turned off in that one spot. Since he's a gelding he probably hasn't been tested for cream? It's very interesting whatever causes it.

I am thinking it might be worth color testing on him. No, he has never been tested. I am sending off a test for my two youngsters soon, I might send a sample for him along with. Cori just looked up his parents on the color calculator, and it doesn't list bay, which is what he is registered as, as a possible result. These are the options listed:

25.00% -
Red Dun
25.00% -
Palomino
25.00% -
Dunalino
25.00% -
Chestnut
Stiffler obviously LOOKS like none of those. But I wonder if there could be something really weird with the sooty gene going on now.
