Gastritis may be defined as an inflammation of the stomach. Atrophic gastritis is a histopathologic entity characterized by chronic inflammation of the gastric mucosa with loss of the gastric glandular cells and replacement by intestinal-type epithelium, pyloric-type glands, and fibrous tissue. Gastric xanthelasma (GX) is a rare tumor-like lesion customarily found as an incidental finding due to its asymptomatic appearance. Cancers also may develop less often from gastric adenomatous polyps, which represent dysplastic epithelium arising in a raised lesion. These early conditions can lead to the development of gastric adenocarcinoma (GC). CMV gastritis pathology outlines. Infection mainly occurs due to reactivation of latent infection.

The development of gastric cancer is associated with a series of pathologic events in which chronic gastritis causes the loss of parietal and mature chief cells (atrophy), the development of mucous neck cell hyperplasia, spasmolytic polypeptide-expressing metaplasia (SPEM), intestinal metaplasia, dysplasia, and, eventually, adenocarcinoma. Atrophy of the gastric mucosa is defined as loss of glandular tissue. the relationship between gastric mucosa atrophy and gastric cancer. Six percent of the patients had lesions that were “indefinite for dysplasia.”. In chronic phase, there is markedly thinned mucosa composed largely of foveolae. 4 In one of the largest series on gastric PGAs, sex distribution was two-thirds female, with an average age of 75 years. Three different types of gastric NET have been described: (1) NETs arising in corpus-predominant atrophic gastritis (Type 1); (2) NETs associated with gastrinoma and MEN-1 syndrome (Type 2; due to inactivating mutations in the MEN1 and REG genes, which provide a negative feedback for gastrin secretion); and (3) sporadic NETs (Type 3). https://twitter.com/RhondaYantiss/status/881989338522898432 ; Sydney system of grading Signet ring cells resemble signet rings.
