Children's Hospital in Los Angeles has a special surgical program for hairy nevuses. They'd be a good first step. There's a little bit of info about them here:

You should take your cues from her own behavior. As a grandparent myself, I understand your worry very well. Still, you would be amazed by the resiliency many children have in dealing with marks of this sort.

thank you for answering me. i don't know what else to say but that she is going to suffer extremely. she is a beautiful little girl with a perfect mind and body except for the mark on her face. how can we help her deal with this? she is going to want to know why her? Why do i have this mark? what did i do wrong? oh dr. rockoff this is so sad for me. we do not have alot of money and we cannot afford expensive counselors or plastic surgeons. when do you think we should seek counseling for her? now? later?
What you are describing is a congenital nevus (mole). These have to watched for change, but the only treatment is plastic surgery, and that is no small matter in a small child. The decision to operate or not is one that needs to be made by experts in pediatric plastic surgery. I assume your granddaughter is seeing such specialists in Albuquerque. Other opinions can be obtained elsewhere, but no doubt anyone would be reluctant to operate at this point.
Without in any way minimizing your concerns, I would point out that kids often do a remarkable job of adapting to obvious deformities. Basically, the people and kids they see every day get used to the way they look, and people stop bringing it up. Her parents will, I'm sure, be vigilant to see that her psychosocial development proceeds properly, and will take action if it's appropriate.
Best.
