title: Violaceous papules on the palms and soles.
abstract: BACKGROUND
  Lichen planus (LP) is a condition with many clinical variants that can be quite varied in their presentation.
  
  
  OBJECTIVE
  We report a case of a 60-year-old woman who presented with a very unusual palmoplantar eruption characterized by violaceous pustule-like papules that was subsequently diagnosed as LP.
  
  
  METHODS
  The above case is reported, along with biopsy results. The patient was subsequently treated with a combination of topical corticosteroids and oral acitretin, and her clinical course was followed.
  
  
  RESULTS
  The eruption responded dramatically to our combination treatment and resolved by the 2-month follow-up.
  
  
  CONCLUSIONS
  Palmoplantar LP is a rare variant of LP that bears little resemblance to its classic LP. This condition responds well to a combination of potent topical corticosteroids and oral acitretin.
