 Almost all benign esophageal diseases are classified as inflammatory reflux diseases, or neoplastic diseases represented by papillomas or leiomyomas. These disorders are easily diagnosed using ordinary white light endoscopy.

 The aim of this report was to investigate the correlation of the magnifying endoscopic findings, using narrow band imaging, and histological findings of benign esophageal lesions, containing ectopic gastric mucosa(cervical)and flat-yellowish irregularities. We postulated that benign esophageal lesions are often accompanied by mild changes of the intra-papillary capillary loop including elongation and/or dilation with no irregularity. We concluded that a differential diagnosis of ectopic sebaceous glands and xanthoma in the esophagus was possible by magnifying endoscopy.

 Therefore, we recommend careful examination and analysis of correlations between endoscopic microvascular and histological findings of various lesions.
