LEUKOCYTE MORPHOLOGICAL ABNORMALITIES (GCA) Flashcards
Darkly staining metachromatic (purple-red) cytoplasmic granules in granulocytes (less often in monocytes and lymphocytes
ALDER-REILLY GRANULES (primary granules)
Abnormal large primary granules
ALDER-REILLY GRANULES (primary granules)
Granules contain degraded mucopolysaccharides due to an enzyme defect
ALDER-REILLY GRANULES (primary granules)
May resemble toxic granules (seen in infections and toxic states)
ALDER-REILLY GRANULES (primary granules)
Alder-Reilly anomaly Mucopolysaccharidoses (MPSs’)
ALDER-REILLY GRANULES (primary granules)
-Gray-blue spindle shaped inclusions in the cytoplasm
MAY-HEGGLIN GRANULES
-Large Dohle body-like inclusions in neutrophils,eosinophils, basophils, and monocytes
MAY-HEGGLIN GRANULES
-The basophilic Dohle body-like leukocyte inclusions are composed of precipitated myosin heavy chains (mRNA)
MAY-HEGGLIN GRANULES
-True Dohle bodies consist of lamellar rows of rough endoplasmic reticulum (rRNA)
MAY-HEGGLIN GRANULES
Giant red, blue, to grayish round inclusions in the cytoplasm
CHEDIAK-HIGASHI GRANULES
Giant lysosomal granules in granulocytes, monocytes,and lymphocytes
CHEDIAK-HIGASHI GRANULES
Cells in the body are affected and exhibit abnormally large lysosomes, which contain fused dysfunctional granules
CHEDIAK-HIGASHI GRANULES
are cytoplasmic inclusions that resemble the fused lysosomal granules
Pseudo-Chediak-Higashi granules
All cancerous
Chediak-higashi granules
Pink or red shaped cytoplasmic granules; found in myeloid and monocytic series only Fused primary granules (peroxidase stain positive)
AUER RODS
bundle of auer rods (seen in acute promyelocytic leukemia(APL); M3; also associated with DIC)
Faggot Cells
Acute myelogenous leukemia (AML, M1 and M2) Acute promyelocytic leukemia (APL, M3) Acute myelomonocytic leukemia (AMML, M4) [AML 1-7]
AEUR RODS
-Appears as dark, blue-black granules in the cytoplasm of neutrophils, usually in segmented and band forms
TOXIC GRANULATION (primary/reactive granules)
