Prolonged inflammation or immunosuppression may cause lymphoproliferative disorders (LPD). Rheumatoid arthritis (RA) itself causes LPD. The immunosuppressive drug methotrexate (MTX) is used widely to treat RA, and is also related to the development of lymphoma. Although the detailed pathogenesis and association are still controversial, care is needed when managing patients with RA treated with MTX. Many reports indicate that discontinuing MTX can induce the regression of LPD. Here, we describe a case of diffuse large B-cell lymphoma that presented with liver involvement in a 67-year-old woman who had used MTX for RA for 15 years.
