Hemophilia causes prolonged coagulation time due to deficiency of intrinsic pathway clotting factors (Factor VIII in Hemophilia A, Factor IX in Hemophilia B). This results in prolonged activated partial thromboplastin time (aPTT) and whole blood clotting time. Leukemia may cause bleeding due to thrombocytopenia or leukostasis but not primarily prolonged coagulation time. Pernicious anemia and malignant neutropenia do not directly affect coagulation cascade.
