title: Iatrogenic Kaposi's sarcoma in nasal cavity: a case report.
abstract: BACKGROUND
  Kaposi's sarcoma (KS) is an uncommon borderline vascular tumor involving mostly the cutaneous and mucosal sites of the body. Among the four distinctly clinicopathological presentations of KS, the iatrogenic form principally occurs in kidney transplant recipients receiving immunosuppressive therapy. It rarely occurs in the head and neck region as primary site or in other groups of patients under immunosuppressive therapy.
  
  
  METHODS
  We present of the case of a patient with right nose KS. The patient had history of systemic lupus erythematosus (SLE) and was under immunosuppressive therapy.
  
  
  CONCLUSIONS
  Once we keep KS in mind, the definite diagnosis can be made using routine histological examination and immunohistochemical study despite the rarity of the disease in this site.
