Non-follicular lymphoma (C83) ICD-10-CM

A form of undifferentiated malignant LYMPHOMA usually found in central Africa, but also reported in other parts of the world. It is commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. B-cell antigens are expressed on the immature cells that make up the tumor in virtually all cases of Burkitt lymphoma. The Epstein-Barr virus (HERPESVIRUS 4, HUMAN) has been isolated from Burkitt lymphoma cases in Africa and it is implicated as the causative agent in these cases; however, most non-African cases are EBV-negative.

A non-Hodgkin lymphoma characterized by a diffuse proliferation of predominantly large neoplastic B lymphocytes. It is the most frequently seen type of non-Hodgkin lymphoma, representing 30%-40% of the cases. Morphologic variants include centroblastic lymphoma, immunoblastic lymphoma, and anaplastic lymphoma. Subtypes/entities include T-cell/histiocyte rich large B-cell lymphoma, primary diffuse large B-cell lymphoma of the central nervous system, plasmablastic lymphoma, primary cutaneous diffuse large B-cell lymphoma, leg type, and ALK-positive large B-cell lymphoma.

Malignant lymphoma composed of large B lymphoid cells whose nuclear size can exceed normal macrophage nuclei, or more than twice the size of a normal lymphocyte. The pattern is predominantly diffuse. Most of these lymphomas represent the malignant counterpart of B-lymphocytes at midstage in the process of differentiation.

A form of non-Hodgkin lymphoma having a usually diffuse pattern with both small and medium lymphocytes and small cleaved cells. It accounts for about 5% of adult non-Hodgkin lymphomas in the United States and Europe. The majority of mantle-cell lymphomas are associated with a t(11;14) translocation resulting in overexpression of the CYCLIN D1 gene (GENES, BCL-1).

A neoplasm characterized by abnormalities of the lymphoid cell precursors leading to excessive lymphoblasts in the marrow and other organs. It is the most common cancer in children and accounts for the vast majority of all childhood leukemias.

A non-Hodgkin or Hodgkin lymphoma that arises from the brain or spinal cord as a primary lesion. There is no evidence of lymphoma outside the central nervous system at the time of diagnosis.

A non-Hodgkin lymphoma composed of monomorphic small, round B-lymphocytes in the lymph nodes. When the lymphoid process predominantly involves the bone marrow and the peripheral blood it is called chronic lymphocytic leukemia. (WHO, 2001)

Small lymphocytic lymphoma occurring in the spleen.
