Abstract:
A 58-year-old man was suspected of having a gastric polyp based on an upper gastrointestinal series. Esophagogastroduodenoscopy showed a gastric polyp, approximately 7mm in diameter, located at the greater curvature of the upper gastric body. Helicobacter pylori testing yielded negative results, and there was no atrophy of the gastric mucosa. Biopsy revealed a well differentiated tubular adenocarcinoma (Group 5). Endoscopic submucosal biopsies were performed, and histopathology revealed a well differentiated tubular adenocarcinoma coexisting with a hyperplastic polyp. Complete en bloc resection was performed, in accordance with the current Japanese guidelines.

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Peptic Ulcer Disease I: Introduction
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.
Peptic ulcers can also be...
Gastritis-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...
Gastritis III: Clinical Manifestations and Management
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...
