title: Large congenital nevus spilus-improved follow-up through the use of in vivo reflectance confocal microscopy.
abstract: BACKGROUND
  Nevus spilus (NS) is a potential precursor of melanoma; the vast majority of cases reported in the literature were histologically classified as superficial spreading melanoma.
  
  
  OBJECTIVE
  To demonstrate the diagnostic value of reflectance confocal microscopy (RCM) in this subtype of congenital nevi.
  
  
  METHODS
  We report a case of a large congenital NS with equivocal clinical and dermoscopic findings in which RCM was applied for diagnosis and follow-up.
  
  
  RESULTS
  There was a good correlation of RCM with histopathology and a lack of dynamic changes during follow-up.
  
  
  CONCLUSIONS
  Our observations indicate that RCM, as a non-invasive tool, can be useful for diagnosis and follow-up of clinically and dermoscopically equivocal NS.
