Working model
of best practices

The Research Committee of Nevus Outreach, Inc. in conjunction with the Expert Committee has proposed a ‘Working’ model of best practices for persons born with Congenital Melanocytic Nevus (CMN). These practices reflect the opinions of the world’s leading experts for CMN but should not be construed as a substitute for the guidance and opinion of you or your child’s physician.


This model applies to every child born with at least one CMN >3cm, >20 satellites, or both. This is to establish a baseline for the patient given the understanding that developmental delays, disease and even death are possible sequelae.

0-6 Months

Ophthalmologic consultation referral

Melanocytic lesions may be found on the retina

An MRI study

with and without gadolinium contrast, of the brain and complete spine before 6 months of age with secondary review by an expert center

  • Melanocytic lesions are defined as Neurocutaneous Melanocytosis (NCM)

  • NCM can be symptomatic or asymptomatic but requires closer monitoring either way

  • Anesthesia to be considered and determined in light of ASA guidelines for pediatrics.

Pediatric Neurology referral

Interpretation and guidance for NCM findings or neurologic symptoms

Pediatric Dermatology referral
  • Interpretation of/and coordination of referrals and findings

  • Regular follow up for skin evaluation

Pediatric Plastic surgery referral

regardless of the ultimate decision, the knowledge of an expert is best in determining if this is even an option for the patient.

  • The only source of valid information on whether removal (if elected as an option) is even possible.

  • The best source of valid information on surgery is a surgeon experienced with nevus.

Before Age 3

Audiologic consultation referral

if failing Newborn Screen or any delayed speech

Child Psychology referral

even if asymptomatic




Genetic counseling referral

CMN is not a germline trait.

Identification of trigger genes and epigenetics is promising but currently more relevant to research than to diagnosis or treatment


These best practices are meant to establish an accurate baseline and to identify those patients who warrant closer follow up due to possible complications. They reflect from the considered opinions of the experts we rely on to guide best outcomes for our constituents.

Nevus Outreach, Inc. is a 501(c)(3) nonprofit corporation headquartered in Jonesboro, Arkansas. Nevus Outreach deals with large congenital melanocytic nevi. Nevus Outreach is dedicated to bringing awareness, providing support, and finding cures for people affected by congenital melanocytic nevi and related disorders.


While Nevus Outreach does not advocate for any one position for every patient, nor any one physician, these best practices represent a consistent basis for initial evaluation of a patient with Congenital Melanocytic Nevus. This is a dynamic model due to the continuing landscape of evidence; however, currently these are our recommendations for our constituency of patients and their providers.
