title: [Normolipemic plane xanthoma, monoclonal gammopathy, anti-lipoprotein activity, hypocomplementemia].
abstract: BACKGROUND
  Normolipaemic plane xanthomatosis is classically associated with a monoclonal gammapathy.
  
  
  METHODS
  We observed this association in a 69-year-old woman. This case was particular since anti-lipoprotein activity due to a monoclonal IgG immunoglobulin was found in the serum with abnormal complement fractions. The paraproteinaemia remained stable after a 2-year follow-up.
  
  
  CONCLUSIONS
  This association is remarkable. The anti-lipoprotein activity of the monoclonal protein should be emphasized in light of the immunological processes involved in the pathogenesis of this association.
