Definition

B-lymphoblastic leukemia/lymphoma (B-ALL/LBL) is a neoplasm of precursor lymphoid cells committed to the B-cell lineage, typically composed of small to medium-sized blast cells with scant cytoplasm, moderately condensed to dispersed chromatin, and inconspicuous nucleoli, involving bone marrow and blood (B-ALL) and occasionally presenting with primary involvement of nodal or extranodal site (B-LBL).

Abstractor Notes

(This code is effective for cases diagnosed 2010 and later. For cases diagnosed prior to 2010 see codes: 9728/3 [lymphomas] or 9836/3 [leukemia].)

B-Acute lymphoblastic leukemia (B-ALL)
Bone marrow is involved in all cases and peripheral blood is usually involved. Extracellular involvement is frequent,

B-Lymphoblastic lymphoma (B-LBL)
The most frequent sites of involvement are the skin, soft tissue, bone and lymph nodes.

Epidemiology and Mortality

Age: primarily disease of children (75% of cases under 6 years age)
Incidence: 1-4.74/100,000 per year worldwide, 10% of lymphoblastic lymphomas
Sex. slight male predominance
Survival: ~80% of children cured; less than 50% of adults cured
