Barrett’s Esophageal Adenocarcinoma Involving a White Globe Appearance within the Long-Segment Barrett’s Esophagus

The diagnosis of Barrett’s esophageal adenocarcinoma (BEA) in patients with Barrett’s esophagus (BE) using endoscopy can be difficult and there are few specific endoscopic findings for BEA. However, white globe appearance (WGA) has been reported to be a specific endoscopic finding for early gastric cancer. We encountered a 51-year-old male patient with BEA exhibiting WGA. Esophagogastroduodenoscopy identified a red, depressed lesion of 10 mm within the long-segment BE (LSBE), while magnifying endoscopy with narrow-band imaging identified WGA. Endoscopic submucosal dissection (ESD) was performed based on our suspicion of BEA. Based on the ESD findings, we diagnosed adenocarcinoma accompanying LSBE histopathologically. WGA was identified, and intraglandular necrotic debris was discovered histologically at the same site. Therefore, WGA may be helpful in the diagnosis of BEA.
