[Malignant non-Hodgkin's lymphomas forming from the germinal-center cells of the lymphoid follicles in baboons from a high-risk stock].
Histological, cytochemical and ultrastructural investigation of immunologically typed B-cell non-Hodgkin's malignant lymphomas (NHL) of primates (model system on baboons) revealed 15 cases of malignant lymphomas originating from germinal centre cells of lymph nodes follicles. By the tumour cell type centroblastic (CB), centroblastic/centrocytic (CB/CC) and centrocytic (CB), malignant lymphomas were distinguished (according to Kiel classification). In case of CB NHL, tumours, as a rule, are of nodular type. Tumours, in which centrocytic infiltration predominates, are characterized by diffuse type of growth in lymphoid and nonlymphoid organs. Generalized process affects mainly lymph nodes and to considerably lower degree involves spleen and nonlymphoid parenchymatous organs.
