title: [Secondary lymphomatous polyposis of the gastrointestinal tract in patients with nodal lymphomas].
abstract: Multiplex lymphomatous polyposis is an uncommon disease characterized by polypoid accumulations of malignant lymphoid cells within the submucosa of long segments of the gastrointestinal tract. Primary gastrointestinal form of disease is referred as an extranodal variant of the entity knows as mantle zone lymphoma. Rarely, this typical lesion may appear as a secondary involvement of the alimentary tract in patients with primary nodal lymphomas. In present article, the clinical, histological features of our two cases of primary nodal lymphoma presenting with gastrointestinal symptoms and secondary involvement of the bowels are discussed. The nodal lymphomas of these patients were classified as a mantle zone and a follicle center cell origin lymphoma. The development of gastrointestinal symptoms occurred 29 and 41 months after the diagnosis. Our cases suggest that lymphomatous polyposis can manifest itself secondarily in patients with nodal lymphomas of not only the mantle cell type. The polypoid lesion might be mediated by lymphocyte homing receptors and the pattern of proliferation can be produced by more than one phenotypically different lymphoma.
