Abstract

To date only a single case of leukemia coincident with the use of methotrexate (MTX) in rheumatoid arthritis (RA) has been reported. We report 2 additional patients with RA, each of whom developed leukemia after receiving short term low dose MTX. Whether these cases represent an adverse effect of MTX treatment has yet to be determined.
