 Malignant lymphoma is frequently detected in the gastrointestinal tract. The morphological characteristics of such lymphoma vary, and thus a pathological diagnosis by a biopsy or via surgical specimen is necessary for the definitive diagnosis of malignant lymphoma. Malignant lymphoma of the small bowel is quite difficult to diagnose even with CT(computed tomography)or positron emission tomography-CT. Capsule endoscopy and balloon-assisted endoscopy are essential for the accurate diagnosis of small bowel lymphomas.

 In addition, magnifying narrow-band imaging is useful to detect malignant lymphoma-specific findings, such as decreased number of vascular networks or irregular vessels, and can help distinguish intestinal malignant lymphomas from benign lymphoid hyperplasia.
