a disorder characterized by an abnormal increase in the number of red blood cells in the blood

any of several blood diseases causing subcutaneous bleeding

presence of abnormal amounts of uric acid salts in the blood; symptom of gout

presence of abnormal amounts of uric acid in the urine; symptom of gout

an abnormally low number of red blood cells in the blood

an abnormal deficiency in all blood cells (red blood cells and white blood cells and platelets); usually associated with bone marrow tumor or with aplastic anemia

anemia characterized by pancytopenia resulting from failure of the bone marrow; can be caused by neoplasm or by toxic exposure

severe anemia in newborn babies; the result of Rh incompatibility between maternal and fetal blood; typically occurs when the child of an Rh-negative mother inherits Rh-positive blood from the father; can be diagnosed before birth by amniocentesis

a rare congenital anemia characterized by pancytopenia and hypoplasia of the bone marrow

anemia resulting from eating fava beans; victims have an inherited blood abnormality and enzyme deficiency

anemia resulting from destruction of erythrocytes

anemia characterized by an increase in the concentration of corpuscular hemoglobin

anemia characterized by a decrease in the concentration of corpuscular hemoglobin

anemia resulting from inadequately functioning bone marrow; can develop into aplastic anemia

a form of anemia due to lack of iron in the diet or to iron loss as a result of chronic bleeding

local anemia in a given body part sometimes resulting from vasoconstriction or thrombosis or embolism

anemia in which the average size of erythrocytes is larger than normal

anemia in which the average size of erythrocytes is smaller than normal

a chronic progressive anemia of older adults; thought to result from a lack of intrinsic factor (a substance secreted by the stomach that is responsible for the absorption of vitamin B12)

any of various anemic conditions that are not successfully treated by any means other than blood transfusions (and that are not associated with another primary disease)

a congenital form of anemia occurring mostly in blacks; characterized by abnormal blood cells having a crescent shape

hemophilia caused by a congenital deficiency of factor VIII; occurs almost exclusively in men

a clotting disorder similar to hemophilia A but caused by a congenital deficiency of factor IX

a form of hemophilia discovered by Erik von Willebrand; a genetic disorder that is inherited as an autosomal recessive trait; characterized by a deficiency of the coagulation factor and by mucosal bleeding

a rare congenital disorder of blood coagulation in which no fibrinogen is found in the blood plasma

serious form of septicemia contracted by a woman during childbirth or abortion (usually attributable to unsanitary conditions); formerly widespread but now uncommon

leukopenia in which the decrease is primarily in number of neutrophils (the chief phagocytic leukocyte)

purpura resulting from a defect in the capillaries caused by bacteria or drugs

the primary form of thrombocytopenia (rather than a shortage of platelets caused by other conditions such as tuberculosis or chemical suppression of bone marrow etc.)

an acute diarrheal disease (especially of chickens) caused by the microorganism that causes hemorrhagic septicemia

a deadly form of septicemia in cattle and sheep; involves high fever and pneumonia; contracted under conditions of exposure or exhaustion (as often happens when the animals are shipped to market)

purpura associated with a reduction in circulating blood platelets which can result from a variety of factors
