Superficial lesions of the pharynx and esophagus have become increasingly important targets for early detection and minimally invasive treatment with advances in endoscopic technology.However, differences in anatomical structure and invasion patterns between these organs result in distinct definitions and diagnostic perspectives for "superficial lesions."In this review, superficial lesions are defined as those confined to the epithelium and subepithelial layer in the pharynx, and to the mucosa and submucosa in the esophagus.These lesions are reconsidered under the unified concept of mucosal disease.Focusing on the sequential process of endoscopic judgment -detection, qualitative diagnosis, and assessment of invasion depth -this article outlines the clinical reasoning that leads to appropriate treatment selection.The aim of this review is to present a practical and consistent endoscopic perspective on how clinicians evaluate and manage mucosal lesions in both the pharynx and esophagus in daily practice.
