Adult T-cell leukemia/lymphoma in donor cells responding to second allogeneic hematopoietic stem cell transplantation using unrelated cord blood: the Nagasaki Transplant Group experience.

The article presents a case study of a 37-year-old man with systemic lymphadenopathy, circulating abnormal lymphocytes, and an elevated serum lactate dehydrogenase level (411 IU/l) and diagnosed with acute T-cell leukemia/lymphoma in donor cells (ATL). The patient underwent second allogeneic hematopoietic stem cell transplantation (HSCT) using unrelated cord blood. Results suggest the potential of a second allo-HSCT for ATL-DC.
