    Auer rods (or Auer bodies) are large, crystalline cytoplasmic inclusion bodies.   Auer rods appear as cytoplasmic pink or red colored thin lines having a needle shaped construction which result from an abnormal fusion of the primary (azurophilic) granules.

    Clinical significance: Auer rods validates myeloid (bone marrow-derived) neoplastic clone and are seen in acute myeloid leukemia, acute promyelocytic leukemia and high-grade myelodysplastic syndromes and myeloproliferative disorders.
