title: Oral metastasis of breast carcinoma diagnosed by fine needle aspiration cytology. A case report.
abstract: BACKGROUND
  Fine needle aspiration cytology (FNAC) is an important technique in the diagnosis of oral and maxillofacial conditions. The purpose of the present paper is to report a case of oral metastasis of breast carcinoma diagnosed by FNAC.
  
  
  METHODS
  A 45-year-old, black woman was referred for evaluation of symptomatic swelling in the left mandible. The medical history revealed that the patient had undergone extensive surgery to remove a lobular carcinoma. She had finished chemotherapy treatment about 5 months earlier. Due to the main diagnostic considerations of metastatic and inflammatory disease, FNAC was performed. The cytologic picture was consistent with a metastatic glandular neoplasm.
  
  
  CONCLUSIONS
  FNAC is a safe, reliable, cost-effective and easy procedure and sometimes eliminates the need for open biopsy.
