(2004) discovered that the cervical and thoracic regionof esophagus of all the birds were composed of smooth muscles while the esophageal glands were present in the lamina propria of the mucosa.
The submucosa, which is denser than the lamina propria, contains mucous tubuloalveolar esophageal glands proper.
The esophageal glands were located in the lamina propria in birds, but in the submucosa layer in mammalians (Sagsoz, 2006).
(2) Vitamin A deficiency results in squamous metaplasia of the esophageal glands leading to secondary infections.
All 14 cases containing NNEM, including squamous epithelium, metaplastic columnar epithelium without goblet cells, and submucosal esophageal glands, showed no staining for IMP3.
Esophagus 460 (450-580) long, surrounded by esophageal glands at its distal part.
In a comparison study of the relationship among the distal end of esophageal longitudinal vessels, the proximal end of gastric mucosal folds, and the most distal end of deep esophageal glands and ducts, Sato et al (17) systematically investigated the entire EGJ in 87 consecutive resection specimens from patients with esophageal squamous cell carcinoma.
In a histologic study of the EGJ in 44 resection specimens for gastric cardiac cancer in Chinese patients, among which the entire EGJ was examined microscopically in 31 cases, Fan et al (23) used the most distal end of squamous mucosa, along with deep esophageal glands and ducts, as the histologic landmarks of the mucosal EGJ.
Recent histopathologic studies have characterized the morphologic features of the mucosal EGJ and defined the following histologic features of the mucosal EGJ as the distal ends of (1) squamous mucosa or islands (Figure 4); (2) deep esophageal glands and ducts (Figure 5); (3) multilayered epithelium (Figure 6) and hybrid glands; and (4) double-layered muscularis mucosa.
Squamous mucosa and deep esophageal glands and ducts are unique to the esophagus and absent in the stomach.
The nomenclature adopted for the esophageal glands (glandulae oesophageae) is another complicating factor in defining the cardia.
Srivastava et al (32) evaluated mucosal biopsy samples from 20 patients with Barrett esophagus and 20 patients with intestinal metaplasia of the gastric cardia; they found that intestinal metaplasia subjacent to squamous epithelium, intestinal metaplasia confined to the superficial mucosa, and presence of esophageal glands or ducts were only seen in samples from patients with Barrett esophagus (with sensitivity of 57%, 40%, and 30%, respectively).
