Definition of Precursor Lymphoid Neoplasms: Neoplasms of immature malignant lymphocytes (lymphoblasts) committed to the B-cell or T-cell lineage. Neoplasms involving the bone marrow and the peripheral blood are called precursor lymphoblastic leukaemias or acute lymphoblastic leukaemias. Neoplasms involving primarily lymph nodes or extranodal sites are called lymphoblastic lymphomas.
Precursor B-lymphoblastic neoplasms
Definition of Precursor B-lymphoblastic neoplasms: Neoplasms of lymphoblasts committed to the B-cell lineage.

2A70.0 B Lymphoblastic leukaemia or lymphoma not elsewhere classified
Definition of B Lymphoblastic leukaemia or lymphoma not elsewhere classified: Precursor B cell neoplasm without defined recurrent genetic abnormality despite appropriate diagnostics
2A70.1 B lymphoblastic leukaemia or lymphoma with t(9:22) (q34;q11.2); BCR-ABL1
Definition of B lymphoblastic leukaemia or lymphoma with t(9:22) (q34;q11.2); BCR-ABL1: A precursor lymphoid neoplasm which is composed of B-lymphoblasts and carries a translocation between the BCR gene on chromosome 22 and the ABL1 gene on chromosome 9. It results in the production of the p190 kd or p210 kd fusion protein. It has an unfavorable clinical outcome.
2A70.Y Other B-lymphoblastic leukaemia/lymphoma with recurrent genetic abnormalities
Precursor T-lymphoblastic neoplasms
Definition of Precursor T-lymphoblastic neoplasms: A neoplasm of lymphoblasts committed to the T-cell lineage, typically composed of small to medium-sized blast cells.
