The nocturnal paroxysmal hemoglobinuria, also known as Marchiafava-Micheli syndrome, is a clonal and acquired disease, caused by a somatic mutation of the PIG-A gene located in the X chromosome and modified a protein involved in the glicosilfosfatidilinositol synthesis that serves as  anchorage for many proteins of the cell membrane;  it is the only hemolytic anemia acquired by defect of the erythrocyte membrane.  It is characterized by a chronic intravascular hemolytic anemia, hemoglobinuria, hyper coagulation, cytopenia due to the marrow failure, thrombosis and rarely leukemic transformation. Having a patient with these characteristics we decided to present the case.
