A Healthy control, normal nasopharynx: 1 WLE, 2 NBI endoscopy, 3 Endoscopic iodine staining. B Chronic hyperplastic nasopharyngitis: 1 WLE, 2 NBI endoscopy showing cobblestone features, 3 Endoscopic iodine staining. Uniform staining was observed. C Nasopharyngeal carcinoma: 1 WLE, 2 NBI endoscopy, 3 Endoscopic iodine staining. The tumor was more obvious than the surrounding normal tissue and inflammatory tissue. The red arrow shows an unstained area after exposure to Lugol's iodine solution, and the blue arrow shows staining with Lugol's iodine solution on the back of the soft palate.
