Figure 2

Histopathological appearance of blood clot in the atrium ((a) H&E; immunostaining for MPO (b), CD42b (c), and CD61 (d)). Most of the small-sized blastic cells in the blood express MPO. CD42b and CD61 label platelets among the blasts, but the blasts are devoid of expression of the megakaryocytic markers.
