Ducts of esophageal glands proper and paneth cells in barrett's esophagus: frequency in biopsy specimens

Summary

The frequency of ducts of esophageal glands proper and Paneth cells was studied in endoscopic biopsy specimens obtained from 49 patients diagnosed as having Barrett's esophagus. Esophageal gland ducts were found in 5 (10%) of the subjects. Paneth cells were observed in 15 (31%) of the 49 patients, being located mainly among mucous cells of intestinalized crypts although a few were also noted in the surface epithelium. Since the presence of esophageal gland ducts in the columnar epithelium-lined mucosa is a pathognomonic feature of Barrett's esophagus, 10% of the patients reviewed were considered to have an unequivocal diagnosis of Barrett's esophagus. Barrett's m ucosa showed histological features similar to incom plete-type intestinal metaplasia of gastric mucosa, except for the presence of Paneth cells.

    Therefore, E-cadherin is one of the most important molecules involved with the Barrett’s carcinogenesis. Pathological examinations in BE have indicated that Goblet cell metaplasia is frequently observed and aberrant Paneth cells are sometimes found in columnar epithelial cells [10]. Specialized columnar epithelium composed of goblet cells, occasionally possesses Paneth cells in the base of the crypt structure.

    The precise locations of about 80% of them were described in the patients' clinical records. The presence of squamous islands and esophageal glands proper or their ducts provides pathognomonic confirmation of an esophageal origin [9-11]. The presence of a double muscularis mucosae in columnar mucosa has never been reported in the gastric cardia but is a strong indicator that a specimen has been obtained from a CLE [12].

    Therefore, the identification of the openings of OGPs into columnar-lined mucosa indicates that squamous-lined mucosa has changed to columnar-lined mucosa. This is a pathognomonic feature of CLO.21–23 Microscopic diagnosis of CLO based on OGPs and related findings (Figure 10) should be borne in mind at histological examination.
