Hi, I'm not a doctor but sounds like she came in contact with something that left a residue on her fingers like that!  I've had that happen before but just cannot recall as of this writing what did this to me.  Of course, a wart remover type product will leave a white mark as you describe, but you mention she didn't come in contact with anything.

Hi, I was trying to google this same question because that same thing JUST happened to me but I have NO idea what it is from or where it could have come from. I am just wondering if perhaps, you or your girlfriend were able to figure out what it was? If I find anything out that may be an answer then I will definitely get back to you.

This happened to me as well. I watch it spread on the back of one finger (above the first joint on one hand) and on the index fingertip. It spread right before my eyes and was accompanied by a slight burning sensation...seemed like a chemical burn. Definitely some type of reaction to something. My question is to what?? Tried to wash/scrub it off with soap, water, and acetic acid (vinegar)...to no avail from what I could tell. One went away within 35 minutes. On the other, its been there for at least an hours.  I just took some pictures, and looked at my skin under a USB microscope. I could clearly see that the white spots on my fingertip were BELOW the surface of the skin (which i why I could not scrub them off), and appear to be small clusters of CRYSTALLIZED material in the skin (which probably is what caused the pain/burning sensation). Perhaps this is uric acid crystallized?? which would make this a symptom of hyperuricemia or minor gout?? I did have a hangover this weekend after watching the Niners game. Don't know. Crazy.
