Flashcards

Leukocytosis

An increase in the number of white blood cells (WBCs) circulating in the blood.

Leukopenia

A decrease in the number of white blood cells (WBCs) circulating in the blood.

Agranulocytosis

A severe reduction in the number of neutrophils, a type of white blood cell.

Pancytopenia

A decrease in all types of blood cells, including red blood cells, white blood cells, and platelets.

What is Leukemia?

Leukemia is a type of cancer that affects blood-forming tissues, primarily the bone marrow, resulting in the production of abnormal white blood cells (WBCs) that can't function properly.

What is Acute Leukemia?

Acute Leukemia is a fast-growing type of leukemia that causes a rapid build-up of immature, non-functional WBCs in the bone marrow. Without treatment, it can be fatal within months.

What is Chronic Leukemia?

Chronic Leukemia is a slower-growing type of leukemia that produces excessive numbers of more mature, but still abnormal, WBCs.

Acute Myelogenous Leukemia (AML) is a type of acute leukemia that affects myeloid precursor cells in the bone marrow.

What is ALL?

Acute Lymphocytic Leukemia (ALL) is a type of acute leukemia that affects immature lymphocytes in the bone marrow. It's the most common type in children and is very responsive to treatment.

Leukemia

A type of blood cancer characterized by an abnormal increase in white blood cells, often neutrophils, leading to symptoms like mouth ulcers, pale necrotic base, and susceptibility to infections.

Leukemoid Reaction

A condition where there's an increase in circulating white blood cells due to a stress response, not cancer.

Acute Lymphoblastic Leukemia (ALL)

A type of leukemia characterized by the presence of leukemic cells only in the bone marrow, not in the blood.

Erythrocyte Deficiency

What is Chronic Lymphocytic Leukemia (CLL)?

A type of leukemia characterized by a gradual accumulation of mature B lymphocytes in the blood, bone marrow, and lymph nodes.

What is Chronic Myelogenous Leukemia (CML)?

A type of leukemia that originates from immature myeloid white blood cells (WBCs), specifically the myeloblasts.

What is the Philadelphia chromosome?

A unique chromosomal abnormality found in about 90% of CML cases, where genetic material from chromosomes 22 and 9 is exchanged.

What is blast crisis in CML?

The phase of CML where leukemic cells lose function and the disease progresses rapidly. This stage is characterized by a high number of blast cells in the bone marrow and blood.

What is the chronic phase of CML?

The phase of CML where leukemic cells proliferate slowly, but are still abnormal and not functional.
