 The patient was a male in his 60s who had been undergoing regular upper gastrointestinal endoscopy after endoscopic treatment for superficial Barrett's esophageal cancer. Seven years after the treatment, a pale brownish area approximately 2mm in size was found on the right wall of the oropharynx. Six months after the pharyngeal lesion was identified, no significant change in size or shape was observed on endoscopy although the brownish color was slightly more obvious on narrow-band imaging examination. One year and three months after the pharyngeal lesion was identified, the lesion became enlarged, and its shape changed abruptly to a flattened elevated lesion with a thick surface. The lesion was excised with an oral resection. Pathological results showed that the lesion was a 300-μm thick squamous cell carcinoma invading the subepithelial layer.
