Helicobacter pylori–negative gastric mucosa– associated lymphoid tissue lymphoma: Magnifying endoscopy findings

Abstract

Gastric mucosa–associated lymphoid tissue lymphoma is uncommon and most patients have an indolent clinical course. The clinical presentation and endoscopic findings can be subtle and diagnosis can be missed on white light endoscopy. Magnifying endoscopy may help identify the abnormal microstructural and microvascular patterns, and target biopsies can be performed. We describe herein the case of a 64-year-old woman with Helicobacter pylori–negative gastric mucosa–associated lymphoid tissue lymphoma diagnosed by screening magnification endoscopy. Helicobacter pylori–eradication therapy was given and she received biological therapy. She is in clinical remission after treatment. The use of magnification endoscopy in gastric mucosa–associated lymphoid tissue lymphoma and its management are reviewed.
