Precursor Lymphoid Neoplasms – Definitions & ICD 11 Codes


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.

  2A70  Precursor B-lymphoblastic neoplasms

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.
