anemia

Blood disorder characterized by a deficiency of red blood cell (RBC) production and hemoglobin, increased RBC destruction, or blood loss (an: without, not; -emia: blood condition)

aplastic anemia

Failure of bone marrow to produce stem cells because it has been damaged by disease, cancer, radiation, or chemotherapy drugs; rare but serious form of anemia

pernicious anemia

Deficiency of erythrocytes resulting from inability to absorb vitamin B12 into the body, which plays a vital role in hematopoiesis

thalassemia

Group of hereditary anemias characterized by less hemoglobin and fewer RBCs in the body than normal; usually seen in people of Mediterranean origin (thalass/o: sea; -emia: blood condition)

hemophilia

Group of hereditary bleeding disorders characterized by a deficiency of one of the factors necessary for coagulation of blood (hem/o: blood; -philia: attraction for)

leukemia

Malignant disease of bone marrow characterized by excessive production of leukocytes (leuk/o: white; -emia: blood condition)

acquired immune deficiency syndrome (AIDS)

Transmissible infection caused by human immunodeficiency virus (HIV) and associated with suppression of the immune system; characterized by increasing susceptibility to infections, malignancies, and neurological diseases

immunodeficiency disease

Any of a group of diseases, either congenital or acquired, caused by a defect in the immune system and generally characterized by susceptibility to infections and chronic diseases

Kaposi sarcoma

Malignancy of connective tissue, including bone, fat, muscle, and fibrous tissue, that is commonly fatal (because the tumors readily metastasize to various organs) and closely associated with AIDS; also called malignant neoplasm of soft tissue (sarc: flesh (connective tissue); -oma: tumor)

lymphadenitis

Inflammation and enlargement of the lymph nodes, usually as a result of infection, obstruction, or removal of lymph channels (lymph: lymph; aden: gland; -itis: inflammation)

lymphedema

Accumulation of fluid in soft tissue resulting from blockage of lymph that prevents lymph fluid from draining, and the fluid buildup leads to swelling; may be caused by inflammation, obstruction, or removal of lymph channels (lymph: lymph; -edema: swelling)

lymphoma

Any malignant tumor of the lymph nodes or other lymph tissue (lymph: lymph; -oma: tumor)

Hodgkin lymphoma

Malignant disease involving the lymph nodes and the spleen; characterized by the presence of unique Reed-Sternberg cells (malignant) in the lymph nodes; also called classical Hodgkin lymphoma or Hodgkin disease

non-Hodgkin lymphoma

A group of more than 20 different types of lymphomas (except Hodgkin lymphoma) that occur in older adults but are not characterized by Reed-Sternberg cells (malignant cells)

mononucleosis

Acute infection caused by Epstein-Barr virus (EBV) and characterized by a sore throat, fever, fatigue, and enlarged lymph nodes (mono-: one; nucle: nucleus; -osis: abnormal condition; increase)
