Which cell type is described on the peripheral smear in this case?

Recognize immature blood cells by their lineage clues. Myeloblasts are large immature myeloid cells with a high nucleus-to-cytoplasm ratio and often prominent nucleoli. A key, diagnostic feature they may show is Auer rods—needle‑like azurophilic inclusions in the cytoplasm—which point to the myeloid lineage and AML. Lymphoblasts look similar at first but usually lack Auer rods and have different cytoplasmic/nuclear details; erythroblasts are erythroid precursors with nucleated red cells, and megakaryoblasts are platelet precursors with distinct nuclear features. Thus, the described cells fit myeloblasts because of their lineage characteristics and, when present, Auer rods.
