I have two dented white patchs above my butt - (like on my lower back) I don't know what they are. Its not vitiligo..or whatever its called because it's not just white..but dented. When I say dented - it like a whole in my skin - like it also a ate part of my skin. I'm also getting two on my butt checks - Does any body know what this is? It white, dented, patches (quater sizes), they don't itch or hurt - but it looks terrible.

I have gone to different doctors many times and they don't know what it is. They took a biopsy but said everything came out normal. They gave me medication..but that didn't help either.

I also have eczema...but I don't think thats related..first because its a different skin disorder and second I;m more sensitive on my legs and arms.

Please help. I don't know what else to do..
