Sheets of myeloblasts with high nuclear-cytoplasmic ratio, prominent nucleoli, and pink rod-shaped inclusions (Auer rods) — pathognomonic for AML.
Labeled regions (3)
- 1Myeloblast
Large cell, scant cytoplasm, fine chromatin, prominent nucleoli.
- 2Auer rod
Pink azurophilic rod = fused primary granules; pathognomonic for AML (esp. APML M3).
- 3Nucleolus
Prominent — classic for blasts.
