title: The development of malignant rhabdoid tumor in a patient with Behçet's disease treated with ciclosporin.
abstract: OBJECTIVE
  To describe a risk of malignant neoplasm in patients with Behçet's disease treated with ciclosporin.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  A patient with Behçet's disease who was treated with ciclosporin developed a mass in his right femur. Histological examination revealed this mass was a malignant rhabdoid tumor.
  
  
  CONCLUSIONS
  This is the first known case of malignant tumor developing in a patient with Behçet's disease treated with ciclosporin. This case underscores the importance of assessing possible risks in the treatment of Behçet's disease with ciclosporin.
