i have a small mole that appeared within the last year. up until now, it has appeared to be unchanging. two days ago, while i was in the shower, it scraped off and is now attached only by a small amount of skin (like a skin tag). before this happened, it was smaller than a pencil eraser, not symmetrical but it looked like it had a definable border. it was tan in color with three tiny black spots. I have several other moles that appeared at the same time, all on my nipples, during pregnancy.
