A smear preparation of a bone marrow aspirate in leukemic-phase in December, 2013. a The peripheral blood showed atypical blast cells with rich plasma, irregular nuclei and conspicuous nucleoli. The percentage of blast cells amounted to 41 % ( ×1,000, Wright–Giemsa stain). b Bone marrow was packed with pleomorphic large cells with abundant and basophilic cytoplasm containing some Auer bodies (×1,000, Wright–Giemsa stain). c These cells are positive for peroxidase staining (×1,000). d These cells are positive for non-specific esterase as monocytes (×1,000)
