Blood Transfusion Induced Opportunistic Adult T Cell Leukaemia/Lymphoma after Hodgkin's Disease

A patient previously treated for Hodgkin's disease (HD) developed secondary adult T cell leukaemia/lymphoma (ATL) after blood transfusion. Immunohistochemical analysis and polymerase chain reaction support the diagnosis. To the best of our knowledge this is the first occurrence of transfusion induced ATL occurring as a second malignancy after treatment for HD. The leukaemia/lymphoma probably developed on the basis of underlying immunosuppression.
