[Multiple lymphomatous polyposis of the gastrointestinal tract: a Tunisian case].

Multiple lymphomatous polyposis is a distinctive primary gastrointestinal lymphoma which endoscopical, histopathological et immunophenotypical characteristics are well known. This lymphoma is rare and its prognosis is bad because of frequency of stage IV patients. We report the case of a 75-year-old male patient with multiple lymphomatous polyposis affecting the rectum, the colon and the stomach associated with an involvement of lymphadenopathies, bone marrow and liver. Treatment by chemotherapy was ineffective and patient dead after 3 sessions of CEOP protocol.
