Abstract
We present two cases of metachronous superficial squamous cell carcinomas at oropharyngeal and hypopharyngeal mucosal sites after chemoradiotherapy for head and neck cancers. These were detected by narrow band imaging combined with a magnifying gastrointestinal endoscopy. In one case, we successfully removed the tumor using endoscopic submucosal dissection. Narrow band imaging combined with magnifying gastrointestinal endoscopy illustrated well-demarcated brownish area and scattered foci of microvascular proliferation. Thus, it may serve as an ideal surveillance mode after chemoradiotherapy for head and neck cancers.Keywords
