There are no pediatric reports regarding the long-term performance of organ transplantation after haplo-HSCT with post-transplant cyclophosphamide (PTCY). A juvenile myelomonocytic leukemia patient, who underwent unmanipulated haplo-HSCT with PTCY from her mother at the age of 3 years, developed chronic liver graft versus host disease (GvHD) which was refractory to specific GvHD treatment. Liver transplantation (LT) from her mother (the donor of her haplo-HSCT) was decided as the next line of treatment. LT was performed on day 540 post-HSCT, and the donor's left lateral segment was appropriately removed and attached to the recipient. The symptoms of GvHD completely regressed in a month. The patient died on day 121 after LT, because of a possible hepato-pulmonary syndrome. Organ failure can develop after allo-HSCT secondary to GvHD and therefore performing HSCT from a haplo-donor may be superior to a matched unrelated donor in terms of subsequent organ transplantation for organ failure. https://ijhoscr.tums.ac.ir/index.php/ijhoscr/article/view/1871 https://ijhoscr.tums.ac.ir/index.php/ijhoscr/article/download/1871/1005
