Large bruises are observed on both arms and on one of the legs. A radiograph of the chest shows lobar consolidation consistent with pneumonia. Culture of expectorated sputum is positive for S. pneumonia bacteria. Laboratory studies are significant for anemia, and a peripheral blood smear shows greatly increased numbers of immature blast cells. A bone marrow biopsy reveals that 28% of cells are lymphoblastic (reference range: 8-11%). 20. Neoplastic proliferation of which of the following is the most likely cause of this patient’s bruises?
