Paroxysmal nocturnal hemoglobinuria terminating in acute granulocytic leukemia.

Paroxysmal nocturnal hemoglobinuria terminating in acute myeloblastic leukemia.

Detection of paroxysmal nocturnal hemoglobinuria clones in patients with myelodysplastic syndromes and related bone marrow diseases, with emphasis on diagnostic pitfalls and caveats.

BACKGROUND The presence of paroxysmal nocturnal hemoglobinuria clones in the setting of aplastic anemia or myelodysplastic syndrome has been shown to have prognostic and therapeutic implications. However, the status of paroxysmal nocturnal hemoglobinuria clones in various categories of myelodysplastic syndrome and in other bone marrow disorders is not well-studied. DESIGN AND METHODS By using...

Intestinal perforation in a patient with paroxysmal nocturnal hemoglobinuria

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare hematologic disorder that manifests with hemolytic anemia, thrombosis, and peripheral blood cytopenias.Acute abdominal pain is one of the PNH clinical manifestations due to venous thrombosis of intra-abdominal sites including hepatic, portal, mesenteric, and splenic veins.Eculizumaband allogeneic bone marrow transplantation (BMT) arethe only w...

Paroxysmal nocturnal hemoglobinuria with acute leukemia.

T HE OCCURENCE of impaired marrow function in paroxysmal nocturnal hemoglobinuria (PNH) has long been recognized. A smaller group of patients, with an initial diagnosis of aplastic anemia, have been noted to develop signs of PNH during the course of their illness.1 Such persons have been said to have “the aplastic anemia-paroxysmal nocturnal hemoglobinuria syndrome.”2 Also evident, in some case...
