I’ve never seen anything like this weird pigmentation on a tomato before - can anyone weigh in?

These are the oldest fruit from near the bottom of the plant. There are no tiny insect holes or breaks in the skin. The fruits are not soft or mushy anywhere.

Otherwise the tomatoes actually look pretty good. They are each at about a pound in weight.
The next fruit up is just at color break and has some unevenness but so far no spots.

That looks like Clear Lake Heirloom Tie-Dye to me.

Sorry I'm not any help except the bad joke.

Pretty funny!

It could be tomato spotted wilt virus:

Or another virus.

Or it might be a fungal fruit rot pathogen (e.g. Anthracnose or Alternaria) that didn't quite succeed in spoiling the fruit because the tomato didn't ripen quickly where it wanted to rot.

We get fruit similar to that on some varieties in my garden. The fruit still seems to be edible, whether or not it tastes as good.

If it were my garden, I would say that if it only happens on a few fruits, especially earlier in the season, it's probably a fungal pathogen. If happens on pretty much every fruit thereafter, it's likely a virus. If it has circles within/overlapping circles, and you can see the lines of the circles within/overlapping the circles, it's likely a virus.

Your case is ambiguous, because I can't see the lines for the circles where they overlap, but it looks a lot like TSWV, still.

@Shule, im watching the other fruit on the plant closely and should have some indication of whether it’s affected within a week or so. No other tomatoes are showing these symptoms and the plant itself seems fine.
So odd!

I agree with Shule.
