Lugol's Dye Spray Chromoendoscopy Establishes Early Diagnosis of Esophageal Cancer in Patients with Primary Head and Neck Cancer

Abstract

Patients with primary head and neck cancer should be considered as high risks for the presence of esophageal cancer. Lugol's dye chromoendoscopy diagnosed high-grade intraepithelial neoplasia, which went unnoticed with standard endoscopy. It permits a more exact detection of lesion boundaries and facilitates a more precise targeting of biopsy fragments.
