A case of pre-B cell acute lymphoblastic leukemia (pre-B ALL) with a dir ins(11;4)(q23;q21q31) chromosome rearrangement is presented. The patient's clinical findings and history were similar to those described for the t(4;11)(q21;q23) subgroup of childhood ALL. These findings suggest that the interfacing of the distal breakpoint at band 4q21 to the proximal breakpoint of band 11q23 represents the primary cytogenetic change observed in this subgroup of ALL.
