[A case of primary lymphoma of the rectum].

The Authors describe a case of primary rectal lymphoma. The primitive involvement of this area is infrequent. The Authors emphasize the difficulty of preoperative diagnosis. The therapeutic approach should allow for correct staging which is only obtained by means of diagnostic studies aimed at excluding multicentric localisation. Sensitivity to radiotherapy has led the Authors to propose it as primary treatment, at least in stage I; surgery must be considered elective in stage II or in cases of need. Chemotherapy is indicated alone or in association with radiotherapy or surgery.
