This case report details two gastric mucosa-associated lymphoid tissue (MALT) lymphoma cases. Effective treatment for MALT lymphoma depends on Helicobacter Pylori presence, requiring tailored therapeutic strategies.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is a distinct subtype of non-Hodgkin lymphoma.
- Helicobacter Pylori infection is a known risk factor and etiological agent in many gastric MALT lymphoma cases.
- Diagnosis can be challenging, often requiring thorough histopathological examination of biopsies.
Observation:
- Two distinct cases of gastric MALT lymphoma are presented.
- Case 1: A patient with indigestion and epigastric pain showed an ulcer with Helicobacter Pylori and MALT.
- Case 2: A patient with hematemesis presented with ulcerations initially attributed to cocaine use, later diagnosed as MALT lymphoma without H. Pylori.
Findings:
- Successful treatment of H. Pylori-positive gastric MALT lymphoma was achieved with eradication therapy.
- Complete remission in the H. Pylori-negative case was obtained through localized radiotherapy.
- The presence or absence of H. Pylori significantly influences the treatment approach and outcomes.
Implications:
- This highlights the critical role of H. Pylori status in guiding treatment decisions for gastric MALT lymphoma.
- For H. Pylori-negative MALT lymphoma, alternative and potentially more aggressive therapies like radiotherapy are necessary.
- Accurate diagnosis and pathogen identification are crucial for effective management of gastric MALT lymphoma.

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...

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.
01:27Gastritis-I: Introduction and Types
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...
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...
