# Primary Gastric and Duodenal Mucosa-Associated Lymphoid Tissue Lymphoma With Symptomatic Anemia

## TL;DR

This paper reports a rare case of a 56-year-old woman diagnosed with lymphoma in both her stomach and duodenum.

## Contribution

The novelty lies in presenting a combined gastric and duodenal MALT lymphoma case, highlighting the rarity and management challenges.

## Key findings

- The patient had mucosa-associated lymphoid tissue lymphoma in both the stomach and duodenum.
- There is a lack of standardized management protocols for duodenal MALT lymphoma.
- The case emphasizes the need for further research into rare lymphoma subtypes.

## Abstract

Mucosal-associated lymphoid tissue (MALT) is a low-grade lymphoma derived from marginal zone B cells in extranodal tissue. Gastric MALT lymphoma is frequently seen; however, duodenal MALT lymphoma is rare, and there is no standardized knowledge up to date about the management of the disease. We present a case of a 56-year-old woman with gastric and duodenal MALT lymphoma.
