What is CMN syndrome?

Congenital melanocytic nevi (CMN) are visible pigmented (melanocytic) proliferations in the skin that are present at birth. CMN are benign, tumor-like malformations resulting from faulty development of pigment cell (melanocyte) precursors in the embryo, and composed of an abnormal mixture of skin elements.

What causes CMN?

CMN are caused by a change in a gene which happens to the baby while it is developing in the womb. A change in a gene is called a mutation. A mutation means that there has been a spelling mistake in the gene, and a gene is just one of the instructions in our body.

Can CMN be cured?

CMN can also be lightened with laser therapy or chemical peels. However, these treatments may not be permanent. Furthermore, lightened moles may also be harder to track for skin cancer risk. The only true “cure” for skin cancer risk of CMN is to remove the mole.

Can congenital nevus turn into melanoma?
