Figure 1

Peripheral blood film showing promyelocytes. The peripheral blood film revealed frequent promyelocytes, most of them with multiple Auer rods. Flow cytometric analysis confirmed that these cells were immature promyelocytes expressing CD45 (dim) CD33 (dim), and CD13 and negative for CD34, HLADR, CD14, CD15, CD64, and CD16. Additional FISH studies confirmed the presence of t(15; 17) PML-RARA fusion seen in acute promyelocytic leukemia.
