I actually had read this exerpt before I posted my question. I thought that the Mycetoma sounded closest. Although, I'm not sure they are really draining anything. But the sharp tips on the bumps look maybe like miniscule scabs, so it's possible. The bumps are hard to the touch, and they don't seem to hurt at all. They seemed to pop up out of nowhere rather quickly, although they are not that large. The cancer description above really bothered me, I suppose it's possible the reflect those symptoms as well. I had a cat die of skin cancer years ago, although it looked nothing like this, but it startled me anyway.
