  54. pernicious anemia  
    a macrocytic-normochromic type of anemia characterized by an inadequate supply of vitamin B12
  55. autoimmune disease
    any disorder characterized by abnormal function of the immune system that causes the body to produce antibodies against itself, resulting in tissue destruction or loss of function.
  56. hemophilia
    a group of hereditary bleeding disorders in which there is a defect in clotting factors neccessary for the coagulation of blood
  57. myelodysplasia
    a disrder within the bone marrow characterized by the proliferation of abnormal stem cells; usually develops into a specific type of leukemia
