title: Post-transplant lymphoproliferative disorder after autologous peripheral stem cell transplantation in a pediatric patient.
abstract: Post-transplant lymphoproliferative disorder (PTLD) is a complication of allogeneic bone marrow transplantation (BMT). Rare cases of PTLD after autologous BMT have been reported only in adults. This case report is the first to describe PTLD in a pediatric patient after autologous peripheral stem cell transplantation (PSCT). This 2-year-old male with stage IV neuroblastoma underwent autologous PSCT. The post-PSCT course was complicated by fever with hematochezia and a lung mass. On day 94 post PSCT, colonoscopy revealed an ulcer due to a PTLD, monomorphic type, B cell phenotype, associated with Epstein-Barr virus. Fine needle aspiration identified the lung mass as neuroblastoma. PTLD can occur in pediatric autologous PSCT recipients, and may occur more frequently in autologous grafts manipulated by T cell depletion or CD34+ cell selection.
