Representative photographs of peripheral blood smear and bone marrow smear. (A) In the peripheral blood smear there is an obviously increased platelet count with the presence of micro- and macro-platelets (white arrows). Erythrocytes reveal an anisocytosis and pronounced anulocytosis (black arrow). Note the presence of regular erythrocytes which represents the erythrocyte population after successful transfusion of two erythrocyte concentrates. (B) In the bone marrow smear there is a clearly increased count of juvenile megakaryocytes (white arrows). A representative megakaryocyte is shown at higher magnification in the inlet. No clustering of megakaryocytes is evident in this section.
