[Primary gastric non-Hodgkin's lymphomas. Presentation of 8 cases].

Eight cases of primary gastric lymphomas encountered in a series of 164 cases of extranodal NHL are analysed. The clinical aspects, the modality of onset and diffusion of the lymphoma, its macroscopic and histopathological features and the different therapeutic approaches are discussed. In particular while the distinction between localised and diffuse forms remains valid, it is pointed out that it is not always possible to treat the former by gastric resection, the latter by chemotherapy. In fact the choice of treatment will often be influenced by the patient's age, the presence of a bulk disease, the inoperability of the lymphoma and its degree of malignancy.
