Anemia, aplastic
Anemia, aplastic: Anemia due to failure of the bone marrow to produce red and white blood cells as well as platelets. Aplastic anemia frequently occurs without a known cause. Known causes include exposure to chemicals (for example, benzene, toluene in glues, insecticides, solvents), drugs (for example, chemotherapy drugs, gold, seizure medications, antibiotics), viruses (for instance, HIV, Epstein-Barr), radiation, immune conditions (for example, systemic lupus erythematosus, rheumatoid arthritis), pregnancy, paroxysmal nocturnal hemoglobinuria, and inherited disorders (for example, Fanconi anemia).

- Anemia, Fanconi
Anemia, Fanconi: A rare, inherited disease that adversely affects all the elements of bone marrow and is associated with malformations of the heart, kidney, and limbs, as well as pigmentary changes of the skin. Fanconi anemia predisposes a person to cancer, particularly to a disturbance of bone marrow growth called myelodysplasia and to acute myeloid […]
- Anemia, iron deficiency
Anemia, iron deficiency: Anemia due to inadequate iron. Iron is necessary to make hemoglobin, the molecule in red blood cells that is responsible for the transport of oxygen. In iron deficiency anemia, the red cells are small and pale. Characteristic features of iron deficiency anemia in children include failure to thrive and increased infections. Iron […]
