Los linfomas de Burkitt asociados a inmunodeficiencia HIV y otros se manifiestan con mayor frecuencia como enfermedad ganglionar. Analysis of the IgV H somatic mutations in splenic marginal zone lymphoma defines a group of unmutated cases with frequent 7q deletion and adverse clinical course.

This item has received. Retrospective analysis of therapeutic response obtained Catovsky D, Matutes E. Morphological classification is based on the identification of the leukaemia cell line and its stage of differentiation. Further, we present information regarding the molecular biological and clinical characteristics of these lymphomas. A clinical evaluation of the International Lymphoma Study Group classification of non-Hodgkin’s lymphoma.


Velpeau performed the autopsy on the patient, observing a greatly enlarged spleen weighing 4. April – June Pages Cytometry B Clin Cytom, 76pp.

Am J Clin Pathol,pp. A FISH analysis of 15 different chromosomes. Translocation t 11;14 q13;q32 in chronic lymphoid disorders. During the latter half of the 20th century, a number of leukaemia subgroups were defined, based on the correlation between their morphology and clinical characteristics, laboratory findings, and response to treatment. A clinicopathological study afb 13 cases. Acute leukaemias are characterised by the uncontrolled proliferation of myeloid or lymphoid progenitor cells.

En el caso de los linfomas B, estas definiciones toman aun mayor valor. Myeloblastic leukaemia with minimal differentiation, or M0-AML, is particularly difficult to diagnose from the morphological point of view because the blasts present both lymphoblastic and myeloblastic features. Finally, the classification must be histopathologically based because it is the pathologist who, in most instances, makes the initial diagnosis.

Molecular heterogeneity lcasificacion splenic marginal zone lymphomas: Immunohistochemical detection of cyclin D1 using optimized conditions is highly specific for mantle cell lymphoma and hairy cell leukemia.

This type of leukaemia has a granulocyte component and a monocyte component in varying proportions and different degrees of maturation. Mutations of the BCL6 proto-oncogene disrupt its negative autoregulation in diffuse large B-cell lymphoma.

Today, despite new classifications based on sophisticated studies, FAB classification is widely used by experts due to its technical simplicity, good diagnostic reliability and cost-effectiveness.


A heterogeneous group that includes an unusual variant of mantle cell lymphoma. The story of chronic myeloid leukaemia historical review. Br J Haematol, 33pp. The other subtype is the pure erythroid variant M6bwhich occurs when dyserythropoiesis is prominent.

Other leukaemia classifications have now gained prominence, such as that proposed by the European Group for the Immunological Characterization of Leukaemias EGILbased on immunophenotyping criteria, 14,15 or more recently, the classification drawn up by the World Health Organisation inupdated inwhich combines morphology cytochemistry, immunophenotyping, clinical presentation, and genetic abnormalities. The role of immunohistology in diagnosis and classification.

The M6 erythroid sub-type is defined by the FAB as a proliferation of dysplastic erythroid elements with a proliferation of blasts of myeloid origin. Evaluation of dr Revised European-American Lymphoma classification confirms the clinical relevance of immunophenotype in cases of aggressive non-Hodgkin’s lymphoma. The classification must be reproducible and clinically relevant, and sufficiently flexible to permit the incorporation of new data. World health organization classification of tumours.
