Fecal matter? Really!!!
Dr. R
Linda:
Pigmenation of sudden onset on the palms almost surely has to be soemthing from the outside, something you touched or handled. I know of no systemic or internal diseases which can cause that kind of problem. Think about what you've been doing, and wait a few days -- the pigment is bound to slough off.
If you still have it in a months' time, have someone check it out for you. But I doubt you'll have to.
Best.

Sounds like feacal matter - improve your hygiene and you'll see a noticable improvement almost immediately.
Good luck,
