Summary
Precursor lymphoid neoplasms comprise lymphoblastic leukemias (ALLs) and lymphoblastic lymphomas (LBLs), of either B- or T-cell origin. As a general rule, ALLs and LBLs are considered biologically equivalent. The distinction between ALLs and LBLs is arbitrary. Bone marrow or peripheral blood blasts ≥ 25% are defined as ALL. Neoplasms with predominant extramedullary involvement, bone marrow, or peripheral blood blasts < 25% are classified as LBL.
