Lymphoproliferative Disorders Flashcards
(42 cards)
Myelos shift…..
left
toward bone marrow
Immature Neutrophils
myelos
bands
Leukemia
cancer of bone marrow, WBC, blood
Leukocytosis
increased WBC count
Neutrophilia
increased neutrophil count
Lymphocytosis
increased lymphocyte count
Leukopenia
decreased leukocyte count
Neutropenia
decreased neutrophil count
Lymphocytopenia
decreased lymphocyte count
Pancytopenia
all blood parts decreased- WBC, RBC, PLT
Phagocytes
cause death of neutrophils
Circulating Granulocyte Pool
circulating in blood
Marginal Granulocyte Pool
adheres to wall of capillaries
Shift to Left
increased demand/ release of immature neutrophils from bone marrow
Causes Left Shift
Acute infections (bacterial)
Acute inflammation and tissue necrosis
leukemia
Reactive Leukocytosis
leukemia like, but not leukemia
very high neutrophil count (50k+)
response to infection
Reactive Leukocytosis can be easily confused with….
Chronic Myelocytic Leukemia (CML)
Causes of Neutropenia
Drugs
infection
leukemia
Leukemia can be indicated by….
very low neutrophil count
Lymphocytes
mononuclear cells derived from lymphoblasts drive humoral (B cell) and cell mediated (T cell) immunity
Causes of Lyphocytosis
acute viral infections
lymphocytic leukemia
Causes of Lymphocytopenia
leukemia
Diagnosing Neoplastic Disorders of Leukocytes
bone marrow biopsy
Diagnosing Lymphomas
lymph node biopsy
