Esophageal Ulcer Seen In An Anterior Section Of The Stomach

Description

Distal esophagus and proximal stomach are presented in an anteriorly opened section that exposes the lumen at the gastroesophageal junction. The esophageal mucosa transitions abruptly to gastric mucosa at the Z line, with the cardia lying immediately inferior to the junction and the lesser curvature coursing along the medial border of the stomach. Near the junction, a focal ulcer interrupts the smooth mucosal surface as a shallow, irregular area of erosion with surrounding erythema, set against visible gastric rugae. Orientation favors an anterior perspective, allowing the ulcer’s relationship to the junction and proximal gastric folds to be read at a glance. Ulceration at or just proximal to the gastroesophageal junction most often raises the clinical context of reflux-related injury, including erosive esophagitis, peptic ulceration, and the spectrum that can accompany Barrett metaplasia. Location matters. A lesion in this zone is a common source of upper gastrointestinal bleeding and can be mistaken for a gastric cardia ulcer on endoscopy unless the squamocolumnar junction and mucosal pattern are carefully identified. The cut-surface presentation helps differentiate esophageal squamous mucosa from gastric columnar mucosa and supports teaching about why biopsies for suspected Barrett are taken in a systematic fashion around the Z line. Gastroenterology and pathology educators can place this illustration alongside endoscopic photographs to reinforce gross-morphology correlates, or in surgical and radiology materials discussing hiatal hernia, reflux disease, and proximal gastric ulcer differentials. It also fits well in patient-facing reflux and ulcer education handouts where a single, labeled view of the junction clarifies where symptoms and bleeding originate.
