Quizplus · Accepted Answer

In ALL, there is a proliferation of lymphoblasts which leads to decreased numbers of normal blood cells. Therefore, the classic morphologic finding in the peripheral blood in ALL is lymphoblasts, decreased platelets, and decreased neutrophils (choice B). Increased WBC and platelets with increased lymphoblasts (choice A) and lymphoblasts with increased platelets and neutrophils (choice C) are not classic findings in ALL. Choice D, increased WBC, platelets, and neutrophils, is not a typical finding in ALL and suggests a different type of leukemia or a reactive process.
