Question

Quizplus · Accepted Answer

The presence of 90% blasts in a peripheral blood smear is indicative of acute leukemia. The negative cytochemical staining with MPO and SBB suggests that the blasts are of lymphoid origin, which is consistent with ALL. AML typically shows staining for MPO, while CLL and CML are primarily disorders of adults and not typically seen in children.
