Study Population

A target sample of 75 patients with LCMN and/or NCM will be enrolled in this registry study. The study is expected to accrue over ≥ 7 years. Currently, an estimated 50 LCMN patients are followed at MSK and we anticipate 25 or more to be referred from outside providers or from new patients seen at MSK. The patient population and the MSK referral base is growing at this time, making this enrollment goal as feasible.

You may qualify if:

  • Patients with LCMN, defined as:
  • Dark-colored patch of skin present at birth
  • Can be located anywhere on the individual's skin
  • May include satellite lesions
  • May be associated with hypertrichosis
  • OR, in absence of cutaneous involvement:
  • histologically or radiographically confirmed CNS melanocytosis.
  • Any age at diagnosis.
  • Signed informed consent by a patient, or parent/legal guardian.
  • Deceased patients can be included provided that parent/legal guardian is contacted at least 6 months after the death of the child and not on the child's birthday or anniversary of death.
  • Pathology review at MSK is not mandatory to confirm the diagnosis of LCMN or NCM. We will not require pathology analysis of leptomeningeal deposits in patients where characteristic skin lesions are present and melanosis of the meninges is radiographically evident. However, if pathology samples have already been obtained as part of a patient's evaluation and treatment at another institution, tissue samples will be requested for review and confirmation of the diagnosis.

You may not qualify if:

  • Informed consent has not been provided.
