We describe a case involving a 53-yr-old male with a marginal zone B-cell lymphoma, associated with an IgM paraprotein and a rheumatoid factor-negative inflammatory polyarthropathy, treated with monoclonal anti-CD20 antibody. During the subsequent 12 weeks, evidence of synovitis reduced to a negligible level, despite no significant change in lymphoma bulk or paraprotein level. The relationship between the lymphoma and the arthropathy, and the likely mechanism of remission of the arthropathy, are discussed in the context of the potential value of anti-CD20 therapy in rheumatoid arthritis.

A 66-year-old woman presents with progressive bilateral swelling of her fingers, elbows, and toes. Initially thought to represent an inflammatory peripheral arthropathy, the patient underwent rheumatology review, but subsequent tissue biopsy confirmed diffuse large B-cell lymphoma. Results of bone marrow biopsy and staging CT were negative. F-FDG PET/CT demonstrates FDG-avid bony and adjacent soft tissue disease limited to the extremities with an excellent metabolic response to primary chemotherapy. This is a rare case of primary bone lymphoma limited to the extremities mimicking an inflammatory peripheral arthropathy.
