Abstractor Notes

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

This leukemia is relatively common in children. The incidence decreases with age, so it is seldom seen in older children and rarely, if never, in adults.

Diagnostic Confirmation

This histology can only be determined by positive genetics and/or immunophenotyping, diagnostic confirmation will always be 3.

B-ALL/LBL with t(12;21)(p13.2;q22.1)

Definition

B-lymphoblastic leukemia/lymphoma with t(12;21) (p13.2;q22.1) is a neoplasm of lymphoblasts committed to the B-cell lineage in which the blasts harbor a translocation between ETV6 (also called TEL) on chromosome 12 and RUNX1 (also called AML1) on chromosome 21.
