Poor peripheral blood stem cell (PBSC) mobilization predicts worse outcome for myeloma and lymphoma patients post autologous stem cell transplant (ASCT). We hypothesize that PBSC harvest using plerixafor and G-CSF in poor mobilizers may improve long-term outcome. We retrospectively analyzed the data on patients who had second PBSC mobilization using plerixafor and G-CSF as a rescue. Nine lympho...

Post-transplant lymphoproliferative disease (PTLD) describes a heterogenous group of lymphoproliferative diseases, occurring as a result of uncontrolled B cell proliferation in the context of post-transplant immunosuppression. The incidence depends on the type of transplant and immunosuppression used; the median time to onset is shorter for recipients of stem cell transplants (2 months) than th...

TO THE EDITOR: The BK virus (BKV) is a human polyomavirus of the Papovaviridae family and causes clinical disease mainly in immunocompromised hosts such as patients infected with human immunodeficiency virus or transplant recipients [1]. Only a few cases of BKV encephalitis have been reported in hematopoietic stem cell (HSC) transplant recipients, with the majority of cases presenting with conc...

isolated extramedullary relapse of chronic myelogenous leukemia (cml) after allogeneic stem cell transplant is rare. there is a case report of a child who developed a granulocytic sarcoma of the maxillary and sphenoid sinuses and lumbosacral spinal cord mass 18 months after allogeneic bone marrow transplant for cml. he was presented with per orbital edema and neurological deficit of lower extre...

In solid organ transplant and in stem cell transplant, the impact of the cytomegalovirus (CMV) serologic status of both the donor and recipient have been the subject of intense scrutiny [1, 2]. In both types of transplants, it has been clear that CMV status can play a significant role in the outcome. In solid organ transplant, CMV donor seropositivity has been well established to lead to an inc...
