Classification and Longitudinal Follow-up of Common Melanocytic Nevi With in Vivo Reflectance Confocal Microscopy

Our working hypothesis is that reflectance confocal microscopy (RCM) can identify distinct subsets of melanocytic nevi that retain their distinctive pattern over time.

Inclusion Criteria:

• Patients visiting the Sheba Medical Center pigmented lesion clinic for skin examination
• Patients having at least three banal-appearing nevi, one on the upper back, one on the lower back and one on the lower extremity (excluding foot), which are amenable for RCM examination.

Exclusion Criteria:

• Patients who are unwilling or medically unable to lie down for 30 minutes.
• Pregnant women
