Although it seems a fair bet that this is a hairless pig issue it may not be. We just have the opportunity to see any skin changes with hairless pigs.
I am still contacting other Skinny owners and rescuers to see if anyone has seen similar spots.
From Judi of MPGR (reprinted with permission):
I have 7 hairless pigs. 2 are not totally albino and have dark eyes. They have no spots. Out of the 5 who are albino, 3 have spots, but as far as I know, they are all round and not raised at all. My oldest is almost all dark skinned, and he (Charlie) is almost 4.
She then added this comment:
Some of the spots are actually oval and not round. But they aren't irregular. And they aren't raised. And they all developed them when young adults, not when they were under a year. I thought that was wierd. Like age spots in humans.
I had thought that where they first came from, they were kept outside? For humans, getting one really bad sunburn can really mess up your skin. Although, if Winky has spots and was born here, he wasn't in the sun ever.
Angel's spots are unchanged since the photos 3 weeks ago. And his weight is still low, but up slightly from a low of 750 to 788 grams. His incisions are completely healed. In fact, the only sign that he's slightly "off" healthwise other than the spots is that he spends a lot of time sleeping head-to-cage-corner, like a pig who is ill.
It appeared very quickly, over the course of 3 or 4 days and was light in colour and looked more wartlike than molelike and was totally raised. Maybe 3/16" diameter. At first I thought it was a war wound. Bliss has many dark moles we monitor - this was different.
We know now to take off any raised mole that appears. Easy surgery, local freezing.
Heart(another of our skinnies) had a suspicious mole removed April 18th - melanocytoma - not malignant but could turn malignant. Her mole was dark, slightly raised in the centre
- ...what, what, what?
Stuart is one of my skinny pigs. He is approximately nine or ten months old now.
About a month ago, he developed a mole on his right shoulder. I took a picture at the time, and have just been watching it since.
More recently, it has started to get darker, and perhaps a bit raised.
A few days ago, he had himself a nasty accident requiring stitches. Since his mole was now starting to send off very slight streaks, I told the vet to pull it off at the same time that he was under to get his stitchs.
The histopath came back today: melanoma.
The margins were clean, though, so this time she got it all.
