Mantle cell lymphoma is a clinically aggressive lymphoma with a poor prognosis. Secondary involvement of gastrointestinal tract by this neoplasm is not uncommon but the primary involvement with distinguished multiple lymphomatous polyposis is unusual. We report a case of mantle cell lymphoma presenting as multiple lymphomatous polyposis of large intestine in a 57-year-old man, who presented with constipation and abdomi-nal pain. A subscquent study showed reginal lymph node and bone marrow involvement. The patient got six courses of systemic CHOP chemotherapy plus rituximab and had complete remisstion. Two years later, he was still alive witout recurrence of the disease.
