MRCP2-2474
A 35-year-old man presents to his primary care physician with persistent heartburn for the past six weeks. He has no known medical conditions and is not taking any medications. Upon examination, there are no notable findings. An endoscopy is performed, revealing gastritis. Biopsies of the stomach confirm the presence of a low-grade mucosa-associated lymphoid tissue lymphoma (MALToma/marginal zone lymphoma), with no evidence of Helicobacter pylori. A CT scan of the chest, abdomen, and pelvis shows no signs of additional disease, and a bone marrow biopsy is normal. The thickness of the stomach wall is not clearly visible.
