Auer Rods.

  • Auer rods are rod-shaped crystalline structures originating from primary granules of myeloid cells.

  • Pathognomonic for acute myeloid leukemia.

  • Pathologically low pH of tumor leukocytes provoked the formation of Auer rods.

  • Bundle of Auer rods: Faggot cells (image 3) are characteristic and strongly indicative of acute promyelocytic leukemia.
