Esophageal adenomas are rare, benign lesions that usually arise in metaplastic columnar epithelium associated with Barrett’s esophagus [116]. Because these lesions have the same potential for malignant degeneration as colonic adenomas, endoscopic or surgical resection is warranted. Adenomas typically appear on barium studies as sessile or pedunculated polyps in the distal esophagus at or near the GEJ [116]. Adenomatous polyps should be differentiated from inflammatory esophagogastric polyps, benign lesions in the distal esophagus that have no malignant potential (see above).

Figure 6.47 Herpes esophagitis. Double‐contrast view shows multiple tiny ulcers (arrows) with surrounding mounds of edema in the mid esophagus. In an immunocompromised patient with odynophagia, this finding should be highly suggestive of herpes esophagitis.
