title: Small cell undifferentiated carcinoma of the pancreas. Report of a patient with tumor marker studies.
abstract: BACKGROUND
  Small cell undifferentiated carcinoma of the pancreas is a rare type of pancreatic neoplasm.
  
  
  METHODS
  The authors report the clinical and pathologic aspects of a patient with this malignant lesion and an extensive serologic and immunohistochemical survey of potential ectopically produced hormones or tumor markers.
  
  
  RESULTS
  Neuron-specific enolase (NSE) emerged as a tumor marker.
  
  
  CONCLUSIONS
  NSE could be valuable in the diagnosis and management of other patients with this rare disease.
