C84
Clinical Information
-
A group of malignant lymphomas thought to derive from peripheral t-lymphocytes in lymph nodes and other nonlymphoid sites. They include a broad spectrum of lymphocyte morphology, but in all instances express t-cell markers admixed with epithelioid histiocytes, plasma cells, and eosinophils. Although markedly similar to large-cell immunoblastic lymphoma lymphoma, large-cell, immunoblastic), this group’s unique features warrant separate treatment.
-
Aggressive nodal or extranodal mature peripheral) t-cell lymphomas that do not belong to the better defined entities of the remainder of mature t-cell lymphomas. This category includes the following variants: lymphoepithelioid cell variant lennert’s lymphoma), follicular variant, and t-zone variant.
-
One of a group of aggressive fast-growing) non-hodgkin lymphomas that begin in mature t lymphocytes t cells that have matured in the thymus gland and gone to other lymphatic sites in the body, including lymph nodes, bone marrow, and spleen.)

-
This type of lymphoma is not frequently seen in the western hemisphere. Clinically, with the exception of anaplastic large cell lymphoma, mature t- and nk-cell lymphomas are among the most aggressive of all hematopoietic neoplasms. Representative disease entities include mycosis fungoides, angioimmunoblastic t-cell lymphoma, hepatosplenic t-cell lymphoma, and anaplastic large cell lymphoma.
