Combination laser therapy as a non-surgical method for treating congenital melanocytic nevi from cosmetically sensitive locations on the body

Where possible, the treatment of choice for medium-sized congenital melanocytic nevi (CMNs) is full-thickness surgical excision. However, for CMNs located on anatomical landmarks (e.g., nipple/areola, eyebrow, auricle, lip, eyelid, and nose), excision can yield esthetically and functionally undesirable results. Thus, treatment of medium-sized CMNs can be challenging. Treatment options for CMNs have been reviewed extensively, and the evolution of laser technology has made lasers a viable treatment option. We previously reported the efficacy of a pulsed dye laser (PDL), which was originally used for vascular malformations, in combination with a Q-switched ruby laser (QsRL) in reducing the number of nevus cells in giant CMNs . PDLs are also highly absorbed by melanin, and the pulse duration is much longer than that of Q-switched pigment-specific lasers. PDLs may have strong photothermolytic effects on surrounding nevus cells not containing melanin. These features...
