The association of rheumatoid arthritis with plasma cell and lymphocytic neoplasms

Abstract

Abstract Previous reports have stressed the association of autoimmune disturbances and lymphoproliferative neoplasms. Here the coexistence of rheumatoid arthritis and plasma cell or lymphocytic neoplasms was investigated. An increased incidence is suggested, as 4 cases of rheumatoid arthritis were found among 112 cases of plasma cell and lymphocytic neoplasms.
