Hello, I have a congenital nevus on my arm/hand/wrist. Its small, about 1-1.5 inches wide and 2-3 inches long and I REALLY, want it removed. As you can see, my wrists are very small so I know I'll need a tissue expander. My questions are as follow: How much will a removal cost? How long will I need to have a tissue expander in? Are there any precautions I have to take considering that the nevus is on my dominant hand? Do I need a doctor that specializes in hand surgeries? Thank you!
