B lymphoblastic leukemia/lymphoma with hyperdiploidy

ICD-O-3 Morphology
9815/3: B Lymphoblastic leukemia/lymphoma with hyperdiploidy
Effective 2010 and later
for cases diagnosed 2010 and later

Usually presents as a leukemia. Lymphomatous presentation is rare.

Alternate Names
ALL with favorable trisomies
High hyperdiploid ALL
A neoplasm of lymphoblasts committed to the B lineage whose blasts contain >50 and usually <66 chromosomes, typically without translocations or other structural alterations. This leukemia is common in children, accounting for about 25% of cases of B-ALL.
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].)

The presenting features are generally similar to those of other patients with ALL. Cases of T-ALL should not be included in this code even though those patients have near tetraploid karyotypes.

Immunophenotyping will confirm that the patient has a B-lymphoblastic B-ALL; the genetic testing provides the information needed to classify this neoplasm as a B lymphoblastic leukemia/lymphoma with hyperdiploidy.
