Aggressive Neuroblastoma in a Pediatric Patient with Severe Hemophilia A. Pediatr Rep. 2021;13(1):125-130. doi:10.3390/pediatric130100182036-75032036-749Xhttp://hdl.handle.net/10400.16/2889Despite the extensive information regarding hemophilia's hemorrhagic complications, the literature on cancer in hemophilia is scarce, especially in pediatric patients. Many uncertainties remain concerning diagnosis and workup. We report a rare case of two severe diseases (neuroblastoma and hemophilia A (HA)) concomitantly present in the same pediatric patient. We highlight that the diagnosis of severe HA did not have a negative impact on the patient's oncologic course. This case also illustrates the significance of the cooperation among different specialties and hospitals when caring for the same patient.enghemophilia Aneuroblastomaperipheral blood stem cell transplantationprophylaxisAggressive Neuroblastoma in a Pediatric Patient with Severe Hemophilia Ajournal article10.3390/pediatric13010018
