[Pathological and clinical study of the primary B and T cell lymphomas of intestines].
Thirty-one cases of primary non-Hodgkin's lymphoma of intestine were typed with monoclonal antibodies UCHL1, Ki-B5, L26 and Ki-MiP. Among them, there were 21 B cell lymphomas and 10 T cell lymphomas. Morphologically, the low-grade MALT lymphomas consisted of centrocyte-like cells, accompanying frequently with lymphoepithelial lesions and residual germinal centers, whereas the T cell lymphomas consisted of pleomorphic lymphoma cells, always accompanying with vascular infiltration, massive necrosis, atrophy of intestinal villi, phagocytosis of reactive histiocytes and epithelitropism. Clinically, T cell lymphomas of intestine occur more frequently in the young adults, usually with fever and diarrhea and is worse in prognosis than that of B cell lymphomas of the similar location.
