T-cell Leukemia
T-cell leukemia describes several different types of lymphoid leukemia which affect T cells. Types include: * Large granular lymphocytic leukemia * Adult T-cell leukemia/lymphoma * T-cell prolymphocytic leukemia In practice, it can be hard to distinguish T-cell leukemia from T-cell lymphoma T-cell lymphoma is a rare form of cancerous lymphoma affecting T-cells. Lymphoma arises mainly from the uncontrolled proliferation of T-cells and can become cancerous. T-cell lymphoma is categorized under Non-Hodgkin lymphoma (NHL) and represents ..., and they are often grouped together.

Lymphoid Leukemia
Lymphoid leukemias are a group of leukemias affecting circulating lymphocytes, a type of white blood cell. The lymphocytic leukemias are closely related to lymphomas of the lymphocytes, to the point that some of them are unitary disease entities that can be called by either name (for example, adult T-cell leukemia/lymphoma). Such diseases are all lymphoproliferative disorders. Most lymphoid leukemias involve a particular subtype of lymphocytes, the B cells. Classification Historically, they have been most commonly divided by the stage of maturation at which the clonal (neoplastic) lymphoid population stopped maturing: * Acute lymphoblastic leukemia * Chronic lymphocytic leukemia However, the influential WHO Classification (published in 2001) emphasized a greater emphasis on cell lineage. To this end, lymphoid leukemias can also be divided by the type of cells affected: * B-cell leukemia * T-cell leukemia * NK-cell leukemia The most common type of lymphoid leukemia is B-cell c ...
