title: A Case of Lichen Sclerosus et Atrophicus With Distinct Erythematous Borders.
abstract: BACKGROUND
  Lichen sclerosus et atrophicus (LSA) is a chronic inflammatory and fibrosing condition that mostly affects the genital mucosa. Nongenital skin may be affected either in isolation or in association with genital involvement. A distinct, brightly red border may be seen but is poorly documented in major dermatology texts. In the case presented, such a border was noted in all of the patient's very extensive lesions.
  
  
  OBJECTIVE
  To draw attention to this clinical manifestation and to stimulate future observations as to its clinical and prognostic significance.
  
  
  RESULTS
  A 67-year-old woman presented with disseminated LSA with genital involvement. All the lesions had a distinct red border. A review of major textbooks available to the authors revealed that the presence of a marginal erythema is regularly not mentioned.
  
  
  CONCLUSIONS
  An erythematous border to LSA may be a notable feature. Its frequency and clinical significance remain to be determined.
