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

Estimated Study Completion Date: September 2013
Estimated Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Study participants
patients 18 or older presenting to the Sheba Medical Center pigmented lesion clinic for skin cancer surveillance. Patients routinely undergo total skin examination that includes clinical and dermoscopic evaluation of skin lesions. Patients also routinely undergo annual total body digital photography that allows identification of new or changing lesions.
Device: RCM imaging
RCM imaging will be performed using a commercially-available RCM (Vivascope 1500, Lucid Inc, Rochester, NY, USA) with 830-nm diode laser with emitting power less than 35 milliwatts


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

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
