Donor cell leukemia (DCL), in which malignancy evolves from donor's stem cells, is an infrequent complication of allogeneic hematopoietic stem cell transplantation. Acute promyelocytic leukemia (APL) derived from donor cell is extremely rare and only four cases have been reported to date. Herein we report a case of donor cell-derived APL developing 32 months after haploidentical peripheral blood stem cell transplantation using posttransplant cyclophosphamide for myelodysplastic syndromes.

Background: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare complement-driven acquired hemolytic anemia with specific presentations of hemoglobinuria, abdominal pain, fatigue, and thrombosis.
Objective: To review the current therapeutic strategies for PNH, including anti-complement therapy and allogeneic hematopoietic cell transplantation (alloHCT), focusing on the tailoring of the approach to the disease subtype.
Results: The outcome of alloHCT varies depending on disease severity, thrombotic history, and response to prior therapies.
