Abstract:
Gastric diffuse large B-cell lymphoma (DLBCL) comprises most of all gastrointestinal lymphomas, accounting for approximately 55%-65% of all cases. This condition predominantly affects male patients and those older than 50 years and is usually aggressive. The clinical presentations are nonspecific and can mimic other diseases. In this report, we present a case of a 66-year-old male patient with a history of hematemesis and melena, with significant weight loss for 3 months. Esophagogastroduodenoscopy (EGD) revealed multiple stomach ulcers. A biopsy taken during EGD, which was followed by immunohistochemical staining, confirmed the diagnosis of non-Hodgkin lymphoma, specifically germinal center B-cell (GCB)-subtype DLBCL. A positron emission tomography (PET) scan was performed, revealing the involvement of the mesenteric lymph nodes and an infiltrative lesion that extended from the stomach to the pancreas. Based on the Ann Arbor staging system, the diagnosis was identified to be stage IV gastric DLBCL. Following diagnosis, we administered rituximab, cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisone (R-CHOP) to the patient.

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.

In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds to M3...
