MALT lymphoma. Presentation of three cases.

Abstract

The Helicobacter Pylori (HP) is a Gram negative bacterium growing in microaerophilic medium that has been tested responsible for diseases of the gastrointestinal tract, mainly of the stomach, where it causes lesions of the gastric mucous of several magnitudes, leading from light acute gastritis to more severe diseases as gastric and/or duodenal ulcer. It has also been associated to two kinds of gastric tumors: adenocarcinoma of intestinal kind, and lymphoid lymphoma associated to mucosa (MALT lymphoma). In our study we reviewed all the cases of gastric neoplasias in a two-year period, finding 3 cases of MALT lymphomas, detected in such studies like panendoscopy to take samples for ureasa testing, and histological studies. That way the diagnosis was confirmed. Among the most frequent symptoms were epigastria pain, weight lost and nauseas. With these results, a therapy was indicated to eradicate the Helicobacter Pylori to avoid other complications and to eliminate the reported in the study gastric lesions. Besides that, the patient reported with a high degree dysplasia lesion was operated and received radiotherapy and chemotherapy.
