• We report the findings of a large localized collection of rheumatoid nodules in the renal cortex of a male patient with long-standing seropositive rheumatoid arthritis. Rheumatoid nodules are a rare occurrence in the urinary tract, with only two previous reports of renal involvement, to our knowledge. A possible relationship, on the basis of immunologically mediated mechanisms, to accompanying chronic pyelonephritis is proposed.
