 Detection of superficial pharyngeal cancer and endoscopic removal are important to maintain organ function and quality of life. Therefore, magnified endoscopy is essential. First, the lesion is screened by non-magnified endoscopy, following which it is examined by magnified endoscopy. By this approach, we found that determining a differential diagnosis between lymphoid follicle, papilloma, dysplasia, and carcinoma by carefully observing the microvessels was not difficult. Further studies are needed to investigate whether magnifying endoscopic classification of the Japan Esophageal Society is beneficial in making a diagnosis of pharyngeal cancer depth in the future. A more precise diagnosis is obtained when the lesion is carefully observed from low to middle power field.
