A 79 year old woman with rheumatoid arthritis presented with multiple subcutaneous skin lesions after she started taking rituximab. Biopsies excluded fungal and bacterial infection, and tissue culture showed negative findings. Histological findings showed vascular granulation and giant cells that were consistent with accelerated rheumatoid nodulosis. Methotrexate is a recognised cause, although links with azathioprine, infliximab, and etanercept have also been documented. Nodules are benign and can be treated with topical tacrolimus. Implicated drug treatments can be continued.
