pigment regrowth

Since the lesions was never completely excised, it's certainly not unexpected that it could grow back.  It's a judgement call.  It probably isn't any different from the lesion removed before although it will be harder to read now.  Scar tissue makes reading pathology much more difficult and things often look "worse" even if they are not.  There isn't a true standard for atypical nevi with possibly the exception of a severely atypical nevus.  That should be removed with 5mm margins.  My own cutaneous oncologist will not leave an atypical lesion on my skin without at least clean margins and he will always excise anything that regrows.  He errs on the side of caution but there are certainly other skilled doctors who might be fine with leaving some cells behind.  At the very least, I would report this to your doc and get his take on it.  I, personally, would probably have it excised again.  But you need to work out with your doctor what is right for YOU.  Again, there is no standard of care so there really is no right answer, only what you can live with.

Best wishes,

My derm would re-excise. No atypical cells would ever have been left there to begin with. We are ultra conservative.
