Fig. 1. The findings of the peripheral blood (PB) smear and bone marrow (BM) aspiration. The PB smear shows leukemic blasts (horizontal arrow) (A). Dysplastic features were found on the PB smear such as marked anisopoikilocytosis in red blood cells (RBCs), pseudo-Pelger-Huet-like neutrophils (vertical arrow), and extreme thrombocytosis with giant and large platelets (B). The BM aspirate smear shows that hematopoietic components are barely visible owing to extreme thrombocytosis (C) and micromegakaryocytes display dyspoietic features of binucleation or non-lobulated shapes (D). Wright-Giemsa; ×200 (C), ×1,000 (A, B, D).
