Endoscopic findings and pathologic characteristics of gastric eosinophilic granuloma: A report of 18 patients

Figure 1 Endoscopic photographs of GEG. A: Retracted ulcer scar on greater curvature and incomplete closure of pylorus; B: A 0.3 cm × 0.4 cm ulcer on gastric notch had whitish base; C: A 3 cm × 4 cm ulcer on inferior wall of gastric body and lesser curvature side. Yellowish green base and tumid ulcer margin; D: A 4 cm × 5 cm giant ulcer on lesser curvature side of gastric antrum and gastric notch had thickened and irregular base. Anterior wall of duodenal bulb was involved; E: The deformed gastric antrum and a 2 cm × 3 cm giant ulcer on gastric antrum and posterior wall of pylorus. The ulcer had mignonette base and black spots. The ulcer margin presented indentation-shaped appearance. Ulcer tissue was rigid and prone to bleed; F: Rough esophageal mucous membrane, blurred vascular net, clear-cut esophageal Z line; G: Higher esophageal Z line.
