I have chronic graft-versus host disease. Side effect of a bone marrow transplant. Mostly effects my skin, which changes color, gets thinner, and in advances stages hardens (aka marbleization).

GVHD is wicked hard to diagnose, monitor. Skin biopsies and normal digital photos.

I've asked my misc doctors (at FHCRC, SCCA, Univ of Wash) over the years about using UV to better diagnose skin conditions.

Now I'm wondering if OCT could also be helpful, perhaps for assessing the scarring.
