title: Acral, pure cutaneous, self-healing, late-onset, cellulitis-like Langerhans cell histiocytosis.
abstract: BACKGROUND
  An unusual and not yet reported clinical presentation of pure cutaneous Langerhans cell histiocytosis (LCH) that was a diagnostic dilemma.
  
  
  OBJECTIVE
  To bring to light the newer presentation of this disease.
  
  
  METHODS
  The case was managed on clinical grounds initially as cellulitis. However, after the investigations and confirmation of the diagnosis, she was managed symptomatically.
  
  
  RESULTS
  Pure cutaneous LCH may manifest in early adulthood with features of cellulitis, erythematous edematous vesicular plaques, and nodules distributed in the flexural acral areas.
  
  
  CONCLUSIONS
  Pure cutaneous LCH may have an acute late onset with unusual morphology as cellulitis, inverse acral distribution, and self-healing.
