Description

Sheets of myeloblasts with high nuclear-cytoplasmic ratio, prominent nucleoli, and pink rod-shaped inclusions (Auer rods) — pathognomonic for AML.

Labeled regions (3)

  1. 1
    Myeloblast

    Large cell, scant cytoplasm, fine chromatin, prominent nucleoli.

  2. 2
    Auer rod

    Pink azurophilic rod = fused primary granules; pathognomonic for AML (esp. APML M3).

  3. 3
    Nucleolus

    Prominent — classic for blasts.
