[Case of malignant lymphoma associated with rheumatoid arthritis].
A 72-year-old woman was admitted to our hospital with exacerbation of dyspnea. She had a history of rheumatoid arthritis (RA) for 26 years, and had been taking methotrexate and prednisolone. Chest radiograph and chest CT revealed marked mediastinal and right axillary lymph node swelling, interstitial shadows and bilateral pleural effusion. A biopsy of the right axillary lymph node for histopathological examination revealed diffuse large B cell lymphoma. The patient achieved complete remission, following 7 cycles of chemotherapy (R-EPOCH). As RA is associated with an increased risk of developing lymphoma, malignant lymphoma must be considered as a possible cause of the mediastinal swelling in a patient with RA.
