Ileal B lymphoma of the marginal zone EUS guided fine needle biopsy diagnosis, Case report

Abstract Text Primary small intestinal lymphoma is a rare condition, accounting for 15–20% of gastrointestinal lymphomas. Small intestinal marginal zone B cell lymphoma (MZL) of mucosa-associated lymphoid tissue (MALT) is an even less common disease accounting for about 15–30% of primary small bowel lymphomas. There are only a few reported cases of ileal MALT lymphomas, which are more frequent in symptomatic patients and with advanced endoscopic findings. This is the first reported case of EUS-guided biopsy diagnosis of an ileal lymphoma.
