How long does melanoma take to spread?
Melanoma can grow very quickly. It can become life-threatening in as little as six weeks and, if untreated, it can spread to other parts of the body.

Small nevi can be removed by simple surgical excision. The nevus is cut out, and the adjacent skin stitched together leaving a small scar. Removal of a large congenital nevus, however, requires replacement of the affected skin.
What is a cellular blue nevus?
Cellular blue nevus (CBN) differs from classic blue nevus since it exhibits a cellular appearance and presents itself with subcutaneous infiltration, intensive pigmentation, and a large size. Thus it can be wrongly diagnosed as melanoma due to atypia criteria that may be present [3–6].
