MODULE 1 Flashcards
(25 cards)
Pale blue oval remnants if free ribosomes or RER
Dohle Bodies
Large blue-black azurophilic cytoplasmic granules; less peroxidase
Toxic Granulation
Nucleus does not segment beyond the two-lobed stage; bilobed/rounded with pince-nez/ dumbbell peanut shape
Pelger-huet Anomaly
Larger than normal neutrophils with six or more nuclear segments
Neutrophil Hypersegmentation
Larger dark cytoplasmic granules in leukocytes; cells function normally
Alder-Reilly Anomaly
Giant fused granules in the neutrophils, monocytes and lymphocytes; engulf but do not kill microorganism
Chediak-Higashi Syndrome
Blue, dohle like cytoplasmic inclusions in ALL; giant platelets are present
May-Hegglin Anomaly
Lack of b-glucosidase resulting to accumulation of glucocerobroside
Gaucher Disease
Deficiency in sphingomyelinase
Niemann-pick disease
In toxic granulation, what granules predominate?
Primary/Azurophilic/Non-specific granules
Directional motility of phagocytes is impaired
Job’s Syndrome
Both random and direct movement of the cells are defective
Lazy Leukocyte Syndrome
There is a chronic infection and formation of granuloma
Chronic granulomatous disease
Low or absent myeloperoxidase enzyme; strong oxidants
Myeloperoxidase Deficiency
Defective leukocyte adhesion
Leukocyte Adhesion Deficiency
Lack of secondary/specific cytoplasmic granules
Specific Granule Deficiency
Increased in WBC count and mimics the blood picture of CML
Neutrophilic Leukemoid Reaction
Presence of immature leukocytes and immature erythrocytes; space occupying lesion in the bone marrow
Leukoerythroblastic Reaction
Result from an unchecked, autonomous clonal proliferation
Myeloproliferative Neoplasm
Characterized by leukocytosis with an increase immature and immature cells of the granulocytic series
Chronic Myelogenous Leukemia
Affecting primarily the erythroid series associated with normal/decreased EPO levels
Polycythemia Vera
Affecting the megakaryocytic lineage with manifestation of thrombocytosis
Essential Thrombocytopenia
Caused by mutations in 60% JAK2, 30% CALR, 5% MPL mutations
Primary Myelofibrosis
Ineffective hematopoiesis and increased apoptosis
Myelodysplastic Syndrome
