Acute myeloid leukemia (AML), also known as acute myelogenous leukemia, is a cancer of the myeloid line of blood cells, characterized by the rapid growth of abnormal white blood cells that accumulate in the bone marrow and interfere with the production of normal blood cells.

Leukopenia (from Greek λευκός (leukos) 'white' and πενία (penia) 'deficiency') is a decrease in the number of leukocytes (WBC). Found in the blood, they are the white blood cells, and are the body's primary defense against an infection. Thus the condition of leukopenia places individuals at increased risk of infection.
This is a list of infectious diseases arranged by name, along with the infectious agents that cause them, the vaccines that can prevent or cure them when they exist and their current status. Some on the list are vaccine-preventable diseases .
The white blood cell differential is a common blood test that is often ordered alongside a complete blood count.The test may be performed as part of a routine medical examination; to investigate certain symptoms, particularly those suggestive of infection or hematological disorders; [5] [6] or to monitor existing conditions, such as blood disorders and inflammatory diseases.
An excess of white blood cells is usually due to infection or inflammation. Less commonly, a high white blood cell count could indicate certain blood cancers or bone marrow disorders. The number of leukocytes in the blood is often an indicator of disease, and thus the white blood cell count is an important subset of the complete blood count.
Rather than predisposing for infections, most of the autoinflammatory disorders lead to excessive inflammation. Many manifest themselves as periodic fever syndromes . They may involve various organs directly, as well as predisposing for long-term damage (e.g. by leading to amyloid deposition).
Eosinopenia is a condition where the number of eosinophils, a type of white blood cell, in circulating blood is lower than normal. [1] Eosinophils are a type of granulocyte and consequently from the same cellular lineage as neutrophils, basophils, and mast cells.
There are also two general causes of cytopenia: autoimmune and refractory. Autoimmune cytopenia is caused by an autoimmune disease when your body produces antibodies to destroy the healthy blood cells. Refractory cytopenia is caused by bone marrow not producing healthy blood cells, and can be a result of cancer.
