title: Endometrial clear cell carcinoma metastatic to the paranasal sinuses: a case report and review of the literature.
abstract: BACKGROUND
  Paranasal sinus metastasis following endometrial carcinoma is extremely rare and a reflection of disseminated disease.
  
  
  METHODS
  We report a case of a 72-year-old woman who presented ethmoid and sphenoid sinus metastasis, 14 months after total abdominal hysterectomy and bilateral salpingo-oophorectomy due to an endometrial clear cell carcinoma.
  
  
  CONCLUSIONS
  One should recognize the possibility of a metastatic disease to the sinuses in patients presenting with associated symptoms.
