title: Fixed drug eruption followed by lichen aureus during abatacept add-on therapy of rheumatoid arthritis.
abstract: BACKGROUND
  Abatacept is a soluble fusion protein approved as add-on drug in rheumatoid arthritis.
  
  
  METHODS
  Here we report the first case of fixed drug eruption followed by lichen aureus due to abatacept in a 67-year-old woman.
  
  
  CONCLUSIONS
  Fixed drug eruption is an unexpected drug reaction for abatacept, since T-cell activation is inhibited.
