Abstract:
We report a new case of primary gastric plasmacytoma. The presenting symptoms was upper gastrointestinal bleeding, and the diagnosis was made preoperatively by means of gastroscopically obtained biopsy material. The demonstration of a single type of IgA-kappa immunoglobulin in plasma cells infiltrating the gastric antrum is considered conclusive evidence of its neoplastic nature. Endoscopically, the gastric plasmacytoma progresses from a benign antral ulcer (0.5 cm in diameter) to an ulcerated mass (7 cm in diameter) in an 8-wk period, suggesting rapid tumoral growth of a kind not described in the revised literature.

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 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.
