We aimed to elucidate the importance of examining the GI tract in patients with ML and assess the overlap rate. Patients and Methods: We analysed 190 patients diagnosed with GI MLs. We compared the overlap rates among the different histopathological types. Results: Twenty-five (13.2%) patients had overlapping GI lesions in more than two segments. The overlap rates were 100% in mantle cell lymphomas (MCL), 27.6% in follicular lymphomas (FL), and 16.3% in diffuse large B-cell lymphomas (DLBCL). MCL, FL, and DLBCL cases showed significantly higher overlap rates than mucosa-associated lymphoid tissue lymphoma cases (p<0.01). About 64.0% of cases of ML with overlapping lesions involved the small intestine. Conclusion: In GI ML cases, it is ideal to examine the entire GI tract by esophagogastroduodenoscopy, colonoscopy, and capsule endoscopy and/or balloon-assisted endoscopy, especially in MCL, FL, and DLBCL.
