title: Partial unilateral lentiginosis.
abstract: BACKGROUND
  We review our experience with nine patients with partial unilateral lentiginosis (PUL), a rare pigmentary disorder.
  
  
  OBJECTIVE
  Our purpose was to define the characteristics of PUL and to discuss the differential diagnosis.
  
  
  METHODS
  The records of nine patients with PUL were reviewed. A literature review on diagnosis, association with other disorders, and differential diagnosis is presented.
  
  
  RESULTS
  PUL is a rare benign disorder that has no known inheritance pattern and has no commonly associated abnormalities.
  
  
  CONCLUSIONS
  Careful history and physical examination may enable the distinction between PUL, nevus spilus, and other more serious genetic disorders associated with lentiginosis.
