Successful treatment of BCG‐related immune reconstitution inflammatory syndrome following ex vivo T‐cell–depleted haploidentical hematopoietic stem cell transplantation: A case report

IRIS is a phenomenon describing localized inflammatory reactions at BCG vaccination site and development of lymphadenopathy as immune system recovers. It is a rare entity in children following haploidentical HSCT. We represent the successful treatment of a case with fluctuating lymphadenopathy due to BCG vaccine during immune reconstitution period following ex vivo T-cell-depleted haploidentical HSCT.
