title: Foreign body reaction mimicking a second primary tumour of the oesophagus.
abstract: OBJECTIVE
  To present a significant complication of pharyngolaryngeal reconstruction, which resulted in diagnostic confusion as it mimicked a second primary tumour of the head and neck.
  
  
  METHODS
  Case report and review of the world literature.
  
  
  METHODS
  A 61-year-old man developed a granulomatous foreign body reaction, mimicking a second primary tumour, at the distal end of a salivary bypass tube, following pharyngolaryngectomy and reconstruction using a tubed anterolateral thigh flap. Clinically and radiologically, this was felt to represent a second primary tumour of the oesophagus, but biopsies revealed full thickness inflammation of the mucosa and granulation tissue. Repeat oesophagoscopy two weeks after removal of the tube showed complete resolution.
  
  
  CONCLUSIONS
  No record of an oesophageal foreign body reaction to a Montgomery salivary bypass tube has previously been reported in the world literature. This report highlights the potential for such a lesion to cause diagnostic confusion with a second primary tumour.
