Classification
A Working Formulation, published within 1982, is primarily descriptive however remains a virtually all widely utilized classification of non-Hodgkin lymphoma now. Low Grade Malignant Lymphoma, little lymphocytic (chronic lymphocytic leukemia) Malignant Lymphoma, follicular, preponderantly microscopic cleaved cell Malignant Lymphoma, follicular, mixed (microscopic cleaved & big cell) Intermediate Grade Malignant Lymphoma, follicular, preponderantly big cell Malignant Lymphoma, diffuse, microscopic cleaved cells Malignant Lymphoma, soft, mixed (microscopic & big cells) Malignant Lymphoma, soft big cells High Grade Malignant Lymphoma, big cell, immunoblastic Malignant Lymphoma, lymphoblastic Malignant Lymphoma, little non-cleaved cells (Burkitt's lymphoma) Miscellaneous Composite Mycosis fungoides Histiocytic Extramedullary plasmacytoma Unclassifiable

A That Classification is the latest classification of lymphoma, published per World Health Organization in 2001. This classification tries to classify lymphomas by cell nature and severity, we.e. a normal cell nature and severity that virtually all closely resembles a tumor. It is classified around tercet big groups: a B cell tumours, the T cell and natural killer cell tumours, Hodgkin lymphoma, and more minor groups: Mature B Cell Neoplasms Chronic lymphocytic leukemia/small lymphocytic lymphoma B-cell prolymphocytic leukaemia Lymphoplasmacytic lymphoma/Waldenström macroglobulinemia Splenic marginal zone lymphoma Plasma cell neoplasms Plasma cell myeloma Plasmacytoma Monoclonal immune globulin deposition diseases Heavy chain diseases Extranodal marginal zone B cell lymphoma (MALT lymphoma) Nodal marginal zone B cell lymphoma Follicular lymphoma Mantle cell lymphoma Diffuse big B cell lymphoma Mediastinal (thymic) big B cell lymphoma Intravascular big B cell lymphoma Primary effusion lymphoma Burkitt lymphoma/leukemia lymphomatoid granulomatosis Mature T cell & Natural Killer (NK) Cell Neoplasms T cell prolymphocytic leukemia T cell big gritty lymphocytic leukemia Aggressive NK cell leukemia Adult T cell leukemia/lymphoma Extranodal NK/T cell lymphoma, rhinal type Enteropathy-nature and severity T cell lymphoma Hepatosplenic T cell lymphoma Blastic NK cell lymphoma Mycosis fungoides/Sezary syndrome Primary dermal CD30-caring T cell lymphoproliferative disorders Primary dermal anaplastic big cell lymphoma Lymphomatoid papulosis Angioimmunoblastic T cell lymphoma Peripheral T cell lymphoma, unspecified Anaplastic big cell lymphoma Hodgkin Lymphoma Nodular lymphocyte-predominant Hodgkin lymphoma Classical Hodgkin lymphoma Nodular sclerosis Mixed cellularity Lymphocyte-rich Lymphocyte depleted Immnuodeficiency-Associated Lymphoproliferative Disorders Associated by using the primary resistant disorder Associated by owning a Human being Immunodeficiency Virus (HIV) Post-transplant Associated using Methotrexate therapy Histiocytic & Dendritic Cell Neoplasms Histiocytic sarcoma Langerhans cell histiocytosis Langerhans cell sarcoma Interdigitating dendritic cell sarcoma/tumour Follicular dendritic cell sarcoma/tumour Dendritic cell sarcoma, unspecified

Prevalence
Based on data from a U.S. National Institutes of Health, lymphomas account for about 5 percent of completely lawsuits of cancer in the United States, & Hodgkin's disease particularly accounts for to a lesser degree 1 percent of everthing subjects of cancer in the United States.
