 The importance of observing the larynx during upper endoscopy has been widely known, and the detection of lesions in these organs by gastrointestinal endoscopists has been increasing. Although we cannot use iodine solution in the pharynx, IEE(image enhanced endoscopy), such as narrow band imaging, plays an important role in the detection of superficial lesions. With IEE, we can detect small lesions and diagnose whether they are benign or malignant according to the region and irregularity of microvessel patterns. When observing brownish lesions, we should distinguish melanosis, lymph nodules, papillomas, and brownish lesions after chemoradiation changes in pharyngeal cancers.
