T-lymphoblastic leukemia/lymphoma (WHO 2008), [1]: 219 previously labeled precursor T-lymphoblastic leukemia/lymphoma (WHO 2001) [1]: 219 is a form of lymphoid leukemia [2] [3] and lymphoma [4] in which too many T-cell lymphoblasts (immature white blood cells) are found in the blood, bone marrow, and tissues, particularly mediastinal lymph nodes. [1]: 635 Labeling as leukemia or lymphoma depends on which feature is more pronounced in a given situation, but has no biological or treatment implication. [1]: 635
It is uncommon in adults, but represents 15% of childhood acute lymphoblastic leukemia and 90% of lymphoblastic lymphoma. [1]: 635
The 2008 terminology dropped "precursor" to avoid linguistic redundancy because the lymphoblast is an immature precursor cell by definition. [1]: 219
