title: Endoscopic follow-up of 3 cases with gastrointestinal tract involvement of mantle cell lymphoma.
abstract: Gastrointestinal (GI) tract involvement of mantle cell lymphoma (MCL) presents as a variety of forms, ranging from multiple lymphomatous polyposis (MLP) to a slight mucosal change. We report 3 cases with GI tract involvement of MCL who were followed-up by endoscopy. The present study shows three new informations. MLP of the esophagus is rare, but it was observed in two of 3 patients who were extensively involved by MCL. Endoscopic follow-up in one patient suggested that lymphoma cells of MCL had invaded the lamina propria to submucosal layer before MLP developed. Two of the 3 cases showed a favorable clinical course with single-agent rituximab therapy.
