Abstract:
Phlegmonous gastritis is a rare and potentially fatal infection of the gastric wall that is often difficult to diagnose due to non-specific symptoms. We report the case of a 56-year-old man with chemotherapy-related neutropenia and immunosuppression, who presented with shock and epigastric pain. Computed tomography revealed diffuse gastric wall thickening, and esophagogastroduodenoscopy revealed extensive mucosal injury, prompting the administration of empiric antimicrobial therapy. He responded well to conservative treatment, with clinical and endoscopic improvements. This case underscores that early clinical suspicion based on endoscopic findings combined with timely therapeutic intervention may be lifesaving in immunocompromised patients.

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...
