Hematopoietic Bone Marrow Transplant to Treat Systemic EBV-positive T-cell Lymphoma of Childhood.

Systemic Epstein-Barr virus-positive T-cell lymphoma of childhood (S-EBV-TCL) is a rare disease for which there is no standard of care. S-EBV-TCL is often associated with hemophagocytic lymphohistiocytosis and is generally thought of on the spectrum of EBV-related disease. For the few reported cases of cure in the literature, hematopoietic stem cell transplant has been required because it is the only treatment that has induced complete remission in patients suffering from EBV-associated T-cell or natural killer cell lymphoproliferative diseases, except hemophagocytic lymphohistiocytosis. Here, we present the case of one patient who was successfully cured with a modified regimen of dose-adjusted EPOCH (etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin), followed by hematopoietic stem cell transplant using a reduced-intensity conditioning regimen.
