title: Teratoma at the esophagogastric junction in a neonate.
abstract: BACKGROUND
  Teratoma at the esophagogastric junction is extremely rare.
  
  
  METHODS
  A 26-day-old male neonate who presented with vomiting and melena.
  
  
  METHODS
  Investigations revealed a mass at the esophagogastric junction, which was excised and confirmed to be a teratoma.
  
  
  RESULTS
  A fistula at the lower end of the esophagus and an esophageal hiatal hernia were observed as complications.
  
  
  CONCLUSIONS
  A careful surgical approach is warranted for a teratoma in esophagogastric junction, to avoid postoperative complications.
