title: Benign schwannoma in supraclavicular region: a false-positive lymph node recurrence of breast cancer suspected by PET scan.
abstract: BACKGROUND
  Positron emission tomography (PET) is the most accurate imaging modalities to detect malignancies. And it helps to take decisions regarding diagnosis, staging, recurrence, and therapeutical management.
  
  
  METHODS
  We report a case of a suspected supraclavicular lymph node relapse, diagnosed by PET-CT in a breast cancer patient. The lymph node was surgically removed in outpatient with local anesthesia. Histological findings diagnosed a benign Schwannoma. In this patient PET-CT failed to distinguish benign tumors from metastatic supraclavicular lymph nodes.
  
  
  CONCLUSIONS
  This case confirms the need to investigate histologically suspected supraclavicular lesions, during breast cancer follow up.
