Lecture - Module 5 Flashcards
a disease, usually of leukocytes, in the blood and bone marrow
LEUKEMIA
Symptoms of short duration
Many immature cell forms in the bone marrow and/or peripheral blood
Elevated total leukocyte count
Acute Leukemia
Symptoms of long duration
Mostly mature cell forms in the bone marrow and/or peripheral blood
Total leukocyte counts that range from extremely elevated to lower than normal.
Chronic Leukemia
is a general term for malignancy that starts in the lymph system, mainly in the lymph nodes.
LYMPHOMAS
Proliferation of malignant lymphocytes which have a basophilic vacuolated cytoplasm with starry sky pattern due to numerous tangible body macrophage that are arrested at certain stages of maturation
HODGKIN LYMPHOMA
presence of Reed Sternberg cell (large binucleated or multinucleated cell resembles owl’s eye appearance with each nucleus bearing a very large nucleolus.
HODGKIN LYMPHOMA
Diffuse large B-cell lymphoma
NON-HODGKIN LYMPHOMA
Reed-Sternberg is absent but mixed population of lymphocytes, histiocytes, eosinophils and some plasma cells are present.
NON-HODGKIN LYMPHOMA
is a form of cancer of the plasma cells.
MYELOMAS
cells overgrows, forming a mass or tumor that is located in the bone marrow.
MYELOMAS
Malignant cells freely trespass the blood brain barrier
Leukemias
Malignant cells are initially confined to the organs containing mononuclear phagocyte cells such as the lymph nodes, spleen, liver, and bone marrow.
Lymphomas
Plasma cells form a mass or tumor that is located in the bone marrow.
Myelomas
________ can spill over into the circulating blood and present a _____ appearing picture on a peripheral blood smear.
lymphomas
leukemic
three broad leukocytes groups according to FAB
- Myelogenous
- Monocytic
- Lymphocytic
Classification of WHO is based on
morphology with immunophenotyping and genetic studies of peripheral blood, bone marrow, and lymph node samples.
ACUTE LEUKEMIAS have _______ and total leukocyte count is __________ or normal or decreased leukocyte count
anemia
usually elevated
remains a lethal disorder, which kills the majority of afflicted adults.
AML
ANLL
most common leukemia subtype
recognized as a heterogenous clonal disorder
ACUTE MYELOID LEUKEMIA
characterized by:
Maturation block and the accumulation of acquired somatic genetic alterations in hematopoietic progenitor cells that alter normal mechanisms of self- renewal, proliferation, and differentiation.
ACUTE MYELOID LEUKEMIA
Undifferentiated blasts, AML— not otherwise categorized
