My first thought was, "could be blue/white veil, which would mean melanoma."

But I've actually had this happen in one of these types of lesions at least once before. Many years ago, one of the ones on my chest temporarily turned blue...and then went back to normal.

Then I glanced down at one of my feet and saw two rather large petechiae.

So I'm thinking this is most likely indolent leukemia, and the purple area is bleeding.

I'm guessing nobody here has any experience with this, because there really is something seriously wrong with me.

Looks like I've had leukemia for around 17 years or so.
