The presenting features are generally similar to those seen in patients with other B-ALLs. Most children with B-ALL with ''BCR-ABL1'' are considered to have high risk on the basis of age and white blood cell count (WBC). Patients tend to have a high WBC count at presentation, and although they may have organ involvement, lymphomatous presentations are rare.
