Gastric MALT-Lymphoma: more than Helicobacter Pylori

In this case report, we describe two cases of gastric mucosaassociated lymphoid tissue (MALT) lymphoma. The first patient, who presented with complaints of indigestion, nausea and epigastralgy, had a solid ulcer on endoscopy. Biopsies showed, next to MALT, presence of Helicobacter Pylori. The second patient was admitted with hematemesis. The multiple ulcerations in his stomach were thought to be cocaine-induced. Only after multiple biopsies the diagnosis of MALT was made. No presence of Helicobacter Pylori could be detected. The first patient was successfully treated with Helicobacter Pylori eradication therapy. Localized radiotherapy resulted in complete remission in our second patient. Hence, in absence of Helicobacter Pylori, more aggressive treatment modalities are needed.

Automated summary

This case report describes two cases of gastric mucosa-associated lymphoid tissue (MALT) lymphoma, with one patient successfully treated with Helicobacter Pylori eradication therapy, and the other achieving complete remission with localized radiotherapy after initial misdiagnosis of cocaine-induced ulcerations. More aggressive treatment modalities may be necessary in the absence of Helicobacter Pylori.
