It's right at the top of where my butt crack starts....It's much more tan than the rest of my skin. It does not itch or bother me whatsoever. Is this something I should be worried about?? Is it just a fungus of sorts?? This is the only place on my body where it is.
I have a couple spots like that on my skin as well - on my face and on my body, but not sure if the facial ones (melasma) are the same as on my body. The melasma on the face is supposedly estrogen-related. I don't think the dark spots on the body are entirely uncommon - I've heard of someone else having it, too.
