[Malignant lymphomas of the intestinal tract. Histological and immunohistological findings in 22 intestinal lymphomas].
The histology and immunohistology of 22 malignant lymphomas of the intestinal tract have been studied using the so-called "Kiel classification". We have found 12 lymphomas with low grade malignancy (lymphocytic, lympho-plasmocytoid, centrocytic, centroblastic-centrocytic) and 10 with high grade (centroblastic, lymphoblastic, immunoblastic). In all cases of lympho-plasmocytoid and immunoblastic lymphoma a monoclonal pattern of intracellular immunoglobulin was identified by the immunoperoxidae method. This technique offers considerable help in distinguishing between (monoclonal) malignant lymphomas and (polyclonal) lympho- or immunoproliferative processes.
