Summary
Primary duodenal mucosa-associated lymphoid tissue (MALT) lymphoma is rare. This case suggests Helicobacter pylori eradication may control duodenal MALToma, even with papilla of Vater involvement.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Primary duodenal mucosa-associated lymphoid tissue (MALT) lymphoma is an exceptionally rare gastrointestinal neoplasm.
- Helicobacter pylori infection is a known risk factor for gastric MALT lymphoma, but its role in duodenal MALToma is less understood.
Observation:
- A 55-year-old woman presented with a MALToma in the descending duodenum.
- The tumor involved the papilla of Vater and showed submucosal infiltration.
- The patient had a concurrent Helicobacter pylori infection in the stomach.
Findings:
- Surgical resection was performed due to the tumor's location and infiltration.
- Postoperative analysis revealed limited submucosal MALToma cell invasion.
- No adjacent tissue invasion or lymph node metastasis was detected.
Implications:
- The findings suggest that Helicobacter pylori eradication might be a viable therapeutic strategy for duodenal MALToma.
- Early diagnosis and treatment, potentially including H. pylori eradication, could prevent disease progression.
- This case highlights the importance of considering H. pylori in the management of duodenal MALToma.
