[Autoimmune hemolytic anemia with a paroxysmal nocturnal hemoglobinuria-like defect: report of one case]

Both autoimmune hemolytic anemia and paroxysmal nocturnal hemoglobinuria are common hemolytic diseases. The former causes hemolysis because of immune disorder, and the latter is an acquired clonal hematologic disorder of stem cells. The two entities are often separate diseases, but can also occur concomitantly or secondary to each other. paroxysmal nocturnal haemoglobinuria-like defect-like defect is a special type of autoimmune haemolytic anaemia and should be distinguished from typical paroxysmal nocturnal haemoglobinuria-like defect.
