Esophageal inlet patches are well defined areas of mucosa which resemble stomach tissue and are pink or salmon colored. [2] The mucosal surface of an esophageal inlet patch is typically flat, [3] but may be slightly raised or slightly depressed. [2]
The usual appearance of portal hypertensive gastropathy on endoscopy is a mosaic-like or reticular pattern in the mucosa. Red spots may or may not be present. The pattern is usually seen throughout the stomach. [2] A similar pattern can be seen with a related condition called gastric antral vascular ectasia (GAVE), or watermelon stomach.
The diagnosis of lymphocytic esophagitis is made by biopsy of the mucosal lining of the esophagus. This is typically achieved at the time of esophagogastroduodenoscopy, a medical procedure wherein an endoscope is inserted through the mouth, into the esophagus, in order to visualize and biopsy the mucosa.

Diagram of the alkaline mucous layer in the stomach with mucosal defense mechanisms. The gastric mucosa is the mucous membrane layer of the stomach, which contains the gastric pits, to which the gastric glands empty. In humans, it is about one mm thick, and its surface is smooth, soft, and velvety.
Gastric erosion occurs when the mucous membrane lining the stomach becomes inflamed. Specifically, the term "erosion" in this context means damage that is limited to the mucosa, which consists of three distinct layers: the epithelium (in the case of a healthy stomach, this is non-ciliated simple columnar epithelium), the basement membrane, and the lamina propria.
Ulcers cause breaks in the mucosa and cause erosion of the sub-mucosa. Zollinger-Ellison syndrome Gastrin levels increase due to tumors, which cause an increase in the gastric fold size. [7] Ménétrier's disease The mucosa pits are in excess causing thickening of the folds. [7] Carcinoma Helicobacter pylori infection Causes inflammation of the ...
The appendix has a mucosa resembling the colon but is heavily infiltrated with lymphocytes. Transition between the different types of epithelium occurs at the junction between the oesophagus and stomach; between the stomach and duodenum, between the ileum and caecum, and at the pectinate line of the anus.

[1] [2] The condition is associated with dilated small blood vessels in the gastric antrum, which is a distal part of the stomach. [1] The dilated vessels result in intestinal bleeding. [3] It is also called watermelon stomach because streaky long red areas that are present in the stomach may resemble the markings on watermelon. [1] [2] [3] [4]
