anemia
Deficiency in erythrocytes or hemoglobin. The most common type of anemia is iron deficiency anemia; it is caused by a lack of iron, which is required for hemoglobin production.
Other types of anemia include:
aplastic anemia
hemolytic anemia
pernicious anemia
sickle cell anemia
thalassemia
hemochromatosis
Excess iron deposits throughout the body.
polycythemia vera
General increase in red blood cells (erythremia).
hemophilia
Excessive bleeding caused by hereditary lack of blood clotting factors (factor VIII or IX) necessary for blood clotting.
purpura
Multiple pinpoint hemorrhages and accumulation of blood under the skin.
leukemia
Increase in cancerous white blood cells (leukocytes).
Four types of leukemia are:
Acute myelogenous (myelocytic) leukemia (AML)
Acute lymphocytic leukemia (ALL)
Chronic myelogenous (myelocytic) leukemia (CML)
Chronic lymphocytic leukemia (CLL)
granulocytosis
Abnormal increase in granulocytes in the blood
mononucleosis
Infectious disease marked by increased numbers of mononuclear leukocytes and enlarged cervical lymph nodes.
multiple myeloma
Malignant neoplasm of bone marrow.
aplastic anemia
hemolytic anemia
pernicious anemia
Lack of mature erythrocytes caused by inability to absorb vitamin B
sickle cell anemia
thalassemia
Inherited defect in ability to produce hemoglobin, leading to hypochromia.
Petechiae
Ecchymoses
Autoimmune thrombocytopenic purpura
is a condition in which a patient makes an antibody that destroys platelets – bleeding time is prolonged.
Acute myelogenous (myelocytic) leukemia (AML)
Autologous bone marrow transplantation (ABMT)
patient serves as his or her own donor for stem cells
Eosinophilia
An increase in eosinophilic granulocytes, seen in certain allergic conditions, such as asthma, or in parasitic infections (tapeworm, pinworm).
Chronic lymphocytic leukemia (CLL).
Abnormal numbers of relatively mature lymphocytes predominate in the marrow, lymph nodes, and spleen. This most common form of leukemia usually occurs in the elderly and follows a slowly progressive course.
Basophilia
An increase in basophilic granulocytes seen in certain types of leukemia.
