title: [Primary malignant lymphomas of the gastrointestinal system].
abstract: The Authors describe their experience regarding eight cases of primary malignant gastrointestinal lymphomas. After having briefly reexamined the epidemiology and the problems coming from the discordances that still exist on various systems of classification and of staging, they put in evidence that it is not always possible to reach a sure preoperative diagnosis on such pathology, and they explain some considerations about the diagnosis, the therapy and the prognosis.
