Abstract:
Gastritis cystica profunda (GCP) is a rare entity characterized by foveolar hyperplasia and cystic dilation of the gastric mucosa and submucosal glands. Its etiopathogenesis remains unknown. It has been associated with chronic inflammatory conditions, such as gastric surgery or bile reflux. The diagnosis is histological, although endoscopic ultrasound (EUS) may be useful for initial suspicion. We present a series of cases from our center, where six cases of GCP were collected between 2012 and 2022, with no history of gastric surgery. The most common locations were the antrum (50%), fundus (33%), and body (17%). Endoscopic findings included polyps ranging from 7 to 50 mm. The treatment was en bloc mucosectomy for lesions ≤20 mm and piecemeal mucosectomy for lesions >20 mm. Recurrence was observed in four patients (67%). Histologically, displaced gastric glands were found in the submucosa with cystic dilation, without dysplastic changes.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
