Mole(?) between toes (photo)

I've had this mole(?) between my two toes for at least 10 years. No changes other than when it gets wet it gets flakey. I had a biopsy done as a precaution but with the holidays hearing anything back is taking forever! I did notice when I had to put polysporin on it after the biopsy it seemed to lighten a bit. It's never bled or gotten itchy. Never really grown.
