title: Hypersensitivity vasculitis induced by cefoperazone/sulbactam.
abstract: BACKGROUND
  Cefoperazone has not been reported to cause vasculitic complications before. Here, we report a case of hypersensitivity vasculitis associated with cefoperazone/sulbactam.
  
  
  METHODS
  A 13-year-old girl with appendicitis developed hypersensitivity vasculitis on the fifth day of cefoperazone/sulbactam therapy. Hypersensitivity vasculitis resolved gradually after removal of the agent on the seventh day and did not recur. Although hypersensitivity vasculitis has multiple causes, coexistence of hypersensitivity vasculitis and cefoperazone treatment, and the quite resolution of the disease after removal of the drug, strongly favours a causative relationship.
  
  
  CONCLUSIONS
  To our knowledge, this is the first report of a hypersensitivity vasculitis associated with cefoperazone.
