MULTIPLE LYMPHOMATOUS POLYPOSIS

Multiple lymphomatous polyposis (MLP) is a distinctive and particularl y rare clinical type of malignant gastrointestinal lymphoma, which is classified as B-cell centrocytic non-Hodgkin's lymphoma. This rare ent ity has been recently reclassified as mantle cell lymphoma. We herein report three additional cases of MLP involving various segments of the gastrointestinal tract. MLP has an aggressive biologic behavior and a relatively poor prognosis and must be treated accordingly as a high-g rade lymphoma with systemic chemotherapy. (C) 1997 Wiley-Liss, Inc.
