title: [Type IV-allergy due to corticosteroids. Rare and paradoxical].
abstract: METHODS
  A 48-year-old woman developed a skin rash after taking glucocorticoids.
  
  
  METHODS
  Positive patch tests revealed type IV allergy (delayed reaction) to several glucocorticoids. In addition an eczema-like rash was produced by an oral provocation test with triamcinolone, although the patch test for this drug had been negative.
  
  
  METHODS
  We recommended avoidance of the positively-tested corticosteroids and issued a corresponding allergy pass.
  
  
  CONCLUSIONS
  Type IV allergy to glucocorticoids is rare but should be considered whenever patients develop a skin rash after the use of corticosteroids.
