A 59-year-old man with an 18-year history of rheumatoid arthritis who had been treated with steroids, methotrexate, and infliximab presented with a high-grade fever, cervical lymphadenopathy, and hepatosplenomegaly. Epstein-Barr virus (EBV) hepatitis was diagnosed based on the liver histology and EBV antibody titer. The symptoms improved temporarily, but five months later, the fever, skin rash, jaundice, and thrombocytopenia relapsed. Bone marrow and liver biopsies demonstrated infiltration with Reed-Sternberg cells. Based on these findings, the patient was diagnosed with other iatrogenic immunodeficiency-associated lymphoproliferative disorder (OIIA-LPD), Hodgkin lymphoma type. This case followed a rare clinical course, in that acute hepatitis preceded the diagnosis of OIIA-LPD.
