title: Successful treatment of lichen planus with low-molecular-weight heparin: a case series of seven patients.
abstract: BACKGROUND
  Lichen planus (LP) is characterized by features of a cell-mediated attack on the epidermis by activated T lymphocytes. CD4+ lymphocytes have been shown to produce endoglycosidase (heparanase), which allows them to penetrate into the subendothelial basal lamina. Low-molecular-weight heparin (enoxaparin) has been shown to inhibit expression of heparanase.
  
  
  METHODS
  Seven patients with LP were treated with enoxaparin.
  
  
  RESULTS
  Five experienced a marked improvement with no side effects.
  
  
  CONCLUSIONS
  Enoxaparin may be an effective treatment for patients with lichen planus.
