[Primary malignant lymphomas of the gastrointestial system].

In a retrospective analysis of 25 cases of primary non-Hodgkin's lymphoma of the gastrointestinal tract, tumors with diffuse histologic pattern predominated. Among the lymphomas of the small and large bowel there was an increased percentage of tumors of lympho-plasmocytoid type. The course of gastric lymphomas is less favourable than that of intestinal lymphomas. No correlation was found in this study, between histologic type and initial stage on the one hand, and the course of the disease on the other.
