Description

This anatomical illustration depicts Grade A erosive esophagitis, characterized by minimal mucosal damage at the gastroesophageal junction. The image shows a small, sharply demarcated erosion confined to a single mucosal fold without bridging across folds. The esophageal lining appears reddened and inflamed, with a visible localized break that highlights the initial stage of mucosal injury caused by acid reflux. The clarity and anatomical accuracy make this illustration particularly useful for medical education on the early detection and diagnosis of erosive esophagitis.
