Abstract
Post-transplant lymphoproliferative disorder (PTLD) is a rare complication following hematopoietic stem cell transplantation (HSCT), with its occurrence post-autologous hematopoietic stem cell transplantation (auto-HSCT) being even rarer. Research on PTLD following auto-HSCT is exceedingly scarce. Here, we present a noteworthy instance wherein a patient with diffuse large B-cell lymphoma (DLBCL) developed PTLD, manifesting as classical Hodgkin lymphoma (cHL) two years after auto-HSCT. Additionally, we conducted an extensive review of existing literature, exploring the current research on PTLD following auto-HSCT and illuminating this scarcely examined area.
