Flashcards in Chap 13, Blood System, Pathology Deck (24)
1

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. 

 

2

Other types of anemia include:

 

aplastic anemia

hemolytic anemia

pernicious anemia

sickle cell anemia

thalassemia

 

3

hemochromatosis

Excess iron deposits throughout the body.

4

polycythemia vera

General increase in red blood cells (erythremia).

5

hemophilia

Excessive bleeding caused by hereditary lack of blood clotting factors (factor VIII or IX) necessary for blood clotting.

6

purpura

Multiple pinpoint hemorrhages and accumulation of blood under the skin.

7

leukemia

Increase in cancerous white blood cells (leukocytes).

8

Four types of leukemia are:

Acute myelogenous (myelocytic) leukemia (AML)

Acute lymphocytic leukemia (ALL)

Chronic myelogenous (myelocytic) leukemia (CML)

Chronic lymphocytic leukemia (CLL)

9

granulocytosis

Abnormal increase in granulocytes in the blood

10

mononucleosis

Infectious disease marked by increased numbers of mononuclear leukocytes and enlarged cervical lymph nodes.

11

multiple myeloma

Malignant neoplasm of bone marrow.

12

aplastic anemia

13

hemolytic anemia

14

pernicious anemia 

Lack of mature erythrocytes caused by inability to absorb vitamin B

15

sickle cell anemia

16

thalassemia

Inherited defect in ability to produce hemoglobin, leading to hypochromia.

17

Petechiae

18

Ecchymoses

19

Autoimmune thrombocytopenic purpura

is a condition in which a patient makes an antibody that destroys platelets -- bleeding time is prolonged.

20

Acute myelogenous (myelocytic) leukemia (AML)

21

Autologous bone marrow transplantation (ABMT)

patient serves as his or her own donor for stem cells

22

Eosinophilia

An increase in eosinophilic granulocytes, seen in certain allergic conditions, such as asthma, or in parasitic infections (tapeworm, pinworm).

23

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.

24

Basophilia

An increase in basophilic granulocytes seen in certain types of leukemia.
