Head and Neck Cancer Arising After Endoscopic Mucosal Resection for Squamous Cell Carcinoma of the Esophagus

Abstract

Among patients who undergo EMR for esophageal carcinoma, those with scattered-type iodine staining of the background mucosa have an increased risk of metachronous head and neck cancer, and should therefore be closely observed. Careful endoscopic observation led to early detection of laryngeal and hypopharyngeal cancer.
