Helicobacter pylori-negative mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach : A clinicopathologic analysis.

The incidence of HP-negative MALT lymphoma is increasing, and in our practice, it is currently more common than HP-associated MALT lymphomas. The pathophysiology of HP-negative MALT lymphoma without chronic gastritis remains unclear. Follow-up data in our study suggest that the prognosis of these cases is excellent despite varied management modalities.
