As stated by Allen,2 about 12.5% of nevi in adults have a junctional component; only a small percentage of junction nevi change to malignant melanoma, but it is difficult to foretell which will become malignant. Most of them remain unchanged and inactive, may regress, or even may develop into some other forms, such as intradermal nevus, compound
