Tóm tắt

Esophageal cell tumors are rare. Esophagogastroduodenoscopy performed on a 48-year-old woman revealed an elevated esophageal lesion and the presence of long-segment Barrett's esophagus. Endoscopic ultrasonography showed a 15 mm homogeneous hypoechoic tumor extending from the lamina propria mucosa to the submucosa. Pathological examination of the biopsy tissue revealed a sheet-like cluster of histiocytoid cells with an abundant eosinophilic granular cytoplasm. Immunohistochemical examination revealed S-100(+) and CD68(+), thus suggesting the diagnosis of a granular cell tumor. The tumor was resected by endoscopic submucosal dissection. Pathologically, the background mucosa was Barrett's mucosa. This is the first reported case of an esophageal granular cell tumor in long-segment Barrett's esophagus.
