Pulmonary arterial hypertension in a child with stage-IV neuroblastoma after autologous hematopoietic stem cell transplantation and review of the literature.

ABSTRACT

PH is a rare condition with high mortality rate after pediatric HSCT. As clinical presentation is non-specific and may mimic other conditions, a high degree of suspicion is required for diagnosis. Here, we present a patient with stage-IV neuroblastoma who developed PAH after autologous HSCT. After exclusion of other causes of PH, we regarded that this condition was secondary to HSCT.
