[Nosography of intestinal lymphomas].

Abstract

Lymphomas can be localized to the gastrointestinal tract and can be primitive or secondary to a systemic lymphoma. Lymphomas can be classified as Hodgkin's and non-Hodgkin's. The latter include IPSID (all of the B-cell) and non-IPSID lymphomas. The involvement of the small intestine in its entire length is a feature of IPSID lymphomas. Non-IPSID lymphomas include MALT-type, which is a B-cell lymphoma, and EATCL, a T-cell lymphoma which is a not infrequent complication of coeliac disease. There are several classifications of lymphomas: the one by Isaacson is the most widely used at present.
